Exaro Studio Software End User License Agreement
Version 2.2 — Effective October 22, 2026 · Last updated October 23, 2026 · Copyright © 2026 Exaro Studio. All rights reserved.
Important — please read carefully.
This End User License Agreement ("EULA" or "Agreement") is a legal agreement between you ("you," "your," or "Licensee") and Exaro Studio ("Exaro," "we," "us," "our," or "Licensor") governing your installation and use of the Exaro Studio software, including Exaro Model.
Exaro Model is a separate product, sold and licensed separately from the Exaro Studio plugin for Unreal Engine. The product-specific terms for it are in Schedule A — Exaro Model at the end of this Agreement. Its Blender add-on is free software under the GNU General Public License, and this Agreement does not apply to it.
By clicking to accept this Agreement, downloading, installing, activating, or using the Software, you agree to be bound by this Agreement. If you do not agree, do not download, install, activate, or use the Software.
This EULA supplements the Exaro Studio Terms of Service. The Terms of Service, Privacy Policy, Acceptable Use Policy, and Refund Policy are incorporated by reference where applicable.
1. Definitions
For purposes of this Agreement:
- "Software" means the Exaro Studio Unreal Engine plugin and related applications, binaries, source code, editor modules, libraries, tools, documentation, configuration files, updates, patches, and other software components supplied by Exaro. "Software" also includes the Exaro Model Engine, but not the Exaro Model Blender Extension (both defined in Schedule A).
- "Runtime Components" means portions of the Software expressly intended by Exaro to be incorporated into and distributed as part of a compiled, cooked, packaged, or otherwise completed Project.
- "Project" means a video game, application, simulation, visualization, virtual-reality experience, interactive experience, film-production project, or similar work created using the Software.
- "Asset" means a 3D model, mesh, texture, material, animation, audio file, visual effect, game-development resource, or other content acquired through the Exaro marketplace. Marketplace Assets are generally governed by the Exaro Asset License rather than this EULA.
- "Seat" means an authorized installation or use of the Software as determined by the license purchased by you.
- "License Key" means a license key, token, account entitlement, or other authorization mechanism used to activate or verify access to the Software.
- "Subscription" means a paid license to the Software for a monthly or yearly period that renews automatically until you cancel it, as set out in section 3 (for Exaro Model, Schedule A, section A2).
- "Updates" means bug fixes, patches, compatibility changes, improvements, and new versions Exaro chooses to make available.
- "Third-Party Services" means external services accessed through or in connection with the Software, including artificial-intelligence providers, model APIs, cloud platforms, development tools, and related services operated by parties other than Exaro.
2. License Grant
Subject to your payment of applicable fees and compliance with this Agreement, Exaro grants you a limited, worldwide, non-exclusive, non-transferable license to install and use the Software according to the license tier you purchased.
You may use the Software to create commercial and non-commercial Projects.
Unless the applicable license tier or product page states otherwise, you may:
- install and use the Software on the number of Seats authorized by your license;
- use the Software in connection with your own Projects or Projects you develop for clients;
- use the Software to create games, applications, simulations, media, and other commercial products;
- modify configuration files and, where Exaro provides source code, make reasonable modifications to that source code for your own authorized development purposes;
- compile or incorporate permitted Runtime Components into Projects; and
- commercially distribute and monetize Projects created using the Software.
Exaro does not claim ownership of your Project merely because the Software was used to create it.
3. Subscriptions and Updates
Your particular license type will be identified when you purchase. For Exaro Model, Schedule A, sections A2 and A3 apply in place of this section where they differ.
Subscription, Renewal, and Cancellation
Exaro Unreal, the Exaro Studio plugin for Unreal Engine, is sold as a Subscription: Individual at US $29 per month or US $249 per year, or Studio at US $999 per year. The price that applies to you is the one shown at checkout. Your subscription includes the Updates released while it is active.
Your subscription renews automatically at the end of each monthly or yearly period, and your payment method is charged the then-current price, until you cancel. You can cancel at any time, in a few clicks, from the account page on exarostudio.com; you do not need to contact us. Cancelling stops the next renewal. You keep access until the end of the period you have already paid for, and we do not refund the rest of that period except as section 18 or the law requires. Before a yearly subscription renews, we email you a reminder 15 to 45 days before it renews with the date and the price. We tell you at least 30 days before a price change applies to you, and you can cancel before it does.
The Version You Keep After 12 Paid Months
Once you have paid for 12 months of Exaro Unreal in total (for example 12 monthly payments, or one yearly payment), you may keep using the version of the Software that is current at that time, without further payment, for as long as you comply with this Agreement, even after your subscription ends. Each further 12 paid months moves the version you keep to the version current at that time.
A kept version gives you its local use only: the plugin's tools, running in your own Unreal Editor. It does not include later Updates. Months that were refunded or charged back do not count.
The Exaro Studio Bundle
The Exaro Studio bundle is an Exaro Unreal subscription and a Exaro Model subscription in one plan at one price: Individual at US $45 per month or US $399 per year, or Studio at US $1,599 per year. An Individual bundle includes the Individual tier of both products and a Studio bundle the Studio tier of both. Exaro Unreal is governed by this Agreement as a Subscription, and Exaro Model by Schedule A, as if each were bought on its own, except that the bundle is billed, renewed, cancelled, and refunded as one subscription, and its paid months count toward the version you keep of each product (this section and Schedule A, section A3).
Distributed Projects
Properly distributed Projects containing authorized Runtime Components do not stop functioning merely because your subscription later ends.
Runtime Components properly incorporated into Projects while you held a valid license may continue to be distributed as part of those Projects, subject to this Agreement.
A license does not automatically include:
- Updates released after your subscription ends;
- separately sold products, such as store components;
- hosted services;
- cloud services;
- AI provider usage; or
- ongoing support,
unless expressly stated at the time of purchase.
4. Seats and Authorized Users
The number of authorized Seats is determined by the license tier you purchased:
- an Individual license is for one natural person, who may activate the Software on up to two machines; and
- a Studio license covers up to five users, who together may activate the Software on up to ten machines.
These tiers apply to Exaro Unreal subscriptions and to the Exaro Unreal part of an Exaro Studio bundle.
Exaro Model has Individual and Studio subscriptions and a free tier; its License Keys and device limits are set out in Schedule A, sections A4 and A15.
Both tiers include the same Software features. A company, organization, or team must use Studio licenses: an Individual license may not be purchased or used by a business entity for use by its employees or contractors, or shared among the members of a team.
You may not share a Seat or License Key for the purpose of avoiding applicable license fees.
If your license allows multiple users or team Seats, each user must comply with this Agreement.
Employees and contractors may use properly licensed Seats on your behalf solely for authorized Projects.
You are responsible for ensuring that persons using Software under your account comply with this Agreement.
Legitimate hardware replacement, migration, or reinstallation does not itself constitute license circumvention, although activation or reactivation may be required.
5. Commercial Projects
You may use the Software to develop Projects for yourself, your employer, or your clients, subject to the Seat limitations applicable to your license.
You may sell, publish, license, distribute, and monetize Projects created using the Software.
You do not owe Exaro a royalty based solely on revenue generated by a Project unless you have separately agreed in writing to a royalty-based license.
A client receiving a completed Project does not need a separate Exaro Software license merely to use the completed Project.
A client or collaborator who needs to independently use the Exaro editor Software to modify or develop the Project must have an appropriate Software license.
6. Runtime Distribution
You may distribute Runtime Components only where Exaro designates those components as redistributable.
Permitted Runtime Components may be distributed:
- as part of a compiled game or application;
- as part of a cooked or packaged Unreal Engine Project;
- as object code or another non-editor form intended for end users; or
- in another form expressly authorized by Exaro.
You may not use this permission to distribute Exaro's editor tools, source code, development libraries, License Keys, activation systems, or reusable Software package as part of another development toolkit or marketplace product.
Your Project should not expose Exaro Software in a form that allows ordinary end users to extract and reuse it as an independent development tool.
7. Marketplace Assets and Game Components
Assets purchased or downloaded from the Exaro marketplace are governed by the applicable Exaro Asset License and product-specific terms.
The fact that the Software can download, install, configure, optimize, or otherwise process an Asset does not change the Asset's license.
If a marketplace product includes both:
- reusable game content; and
- Exaro proprietary Software,
the reusable game content may be incorporated into Projects according to its Asset License, while Exaro proprietary Software remains subject to this EULA.
Where terms directly conflict, the more product-specific license controls for the applicable component.
8. Source Code
Where Exaro provides source code as part of the Software, you may inspect and modify that source code as reasonably necessary to:
- integrate the Software with your Project;
- troubleshoot your Project;
- maintain compatibility;
- compile the Software; or
- make internal modifications for your authorized use.
Providing source code does not transfer ownership of the underlying Exaro source code to you.
You may not publish, sell, sublicense, publicly post, or otherwise distribute Exaro source code or substantial portions of it except as expressly permitted in writing.
You may not place Exaro proprietary source code in a public repository.
You retain any rights you independently hold in original code that you write.
To the extent your modifications contain or are derivative of Exaro Software, distribution of those modifications remains subject to this Agreement.
9. License Restrictions
Except where applicable law expressly gives you a right that cannot be restricted, you may not:
- sell, sublicense, rent, lease, redistribute, publish, or transfer the Software as a standalone product;
- provide unlicensed persons with access to the Software;
- share, publish, sell, or transfer a License Key;
- circumvent Seat limits or activation mechanisms;
- bypass licensing, payment, authentication, or entitlement controls;
- remove or obscure copyright, trademark, license, or proprietary notices;
- make Exaro proprietary source code publicly available;
- distribute the editor or development portions of the Software as part of another toolkit, plugin pack, template, marketplace product, or software-development package;
- operate the Software as a hosted service, service bureau, white-label product, or competing software service for third parties unless Exaro expressly authorizes such use;
- systematically copy Exaro proprietary source code or user-interface elements for the purpose of creating a substantially similar competing software product;
- reverse engineer, decompile, or disassemble portions of the Software for which source code has not been provided, except to the extent applicable law expressly permits such activity notwithstanding this restriction;
- access Exaro systems in an unauthorized manner; or
- use the Software in violation of the Exaro Acceptable Use Policy or applicable law.
Nothing in this section prohibits you from independently developing competing software without copying or misusing Exaro's proprietary Software or confidential material.
10. Activation and License Verification
The Software may require activation or periodic license verification.
For those purposes, Exaro may process information reasonably necessary to:
- validate your License Key or account entitlement;
- verify your license tier and whether your subscription is active;
- enforce the number of licensed Seats;
- identify an authorized device or installation;
- prevent fraud or license abuse; and
- maintain licensing records.
This may include a License Key, account or entitlement identifier, device or machine identifier, Software version, and limited technical information necessary for licensing.
The handling of personal information associated with activation is governed by the Exaro Privacy Policy.
Activation systems may include reasonable offline grace periods or other mechanisms determined by Exaro.
Schedule A, sections A6 and A7 state what the Exaro Model Engine sends for activation, verification, and building.
Exaro may require reactivation following material hardware changes, reinstallation, account changes, or other events reasonably affecting license verification.
11. Expiration, Refunds, and License Enforcement
When your subscription ends, the Software stops offering you Updates, and the features your subscription unlocked stop at the next license check, except the version you keep under section 3.
If a purchase is validly refunded, the license associated with the refunded purchase terminates, its License Key is revoked automatically, and you must stop using the refunded Software.
If you materially violate this Agreement, Exaro may suspend access to Exaro-hosted services, accounts, downloads, future Updates, or other services as permitted by applicable law.
Exaro will not use technical measures to remotely disable locally installed Software as a contractual enforcement remedy where such electronic self-help is prohibited by applicable law.
Nothing in this section prevents ordinary expiration of a time-limited entitlement or other license behavior that is lawful and clearly disclosed as part of the purchased license.
12. Updates and Changes
Exaro may make Updates available from time to time.
Updates may:
- fix bugs;
- modify features;
- add features;
- remove obsolete functionality;
- address security issues;
- support newer Unreal Engine or Blender versions; or
- discontinue support for older environments.
Updates are included while your subscription is active. Updates released after that require an active subscription (section 3; for Exaro Model, Schedule A, section A2).
Exaro does not guarantee that every version of the Software will support every past or future version of Unreal Engine, Blender, Windows, third-party plugin, API, model provider, or other dependency.
Supported configurations will be identified in applicable documentation or product information.
Nothing in this section limits mandatory rights concerning updates or conformity that applicable consumer law gives you.
13. Third-Party Services and Bring-Your-Own API Keys
The Software may allow you to connect to Third-Party Services such as artificial-intelligence APIs, model providers, cloud platforms, or development services.
You may be required to supply your own API keys, credentials, accounts, or subscriptions.
Unless expressly stated otherwise, you are responsible for:
- obtaining access to the Third-Party Service;
- paying charges imposed by the Third-Party Service;
- protecting your credentials;
- complying with the provider's terms;
- evaluating the provider's privacy and data-handling practices; and
- determining whether the provider is appropriate for your use case.
Third-Party Services are not controlled by Exaro. Their:
- availability;
- pricing;
- rate limits;
- models;
- policies;
- output quality;
- content restrictions; and
- functionality
may change independently of Exaro.
Exaro is not responsible for a Third-Party Service discontinuing or changing its service.
Where reasonably practical, Exaro may modify integrations in response to third-party changes, but Exaro does not guarantee indefinite compatibility with any particular provider.
14. AI-Generated Outputs
The Software may facilitate requests to artificial-intelligence or machine-learning services.
AI-generated output can contain errors, omissions, security vulnerabilities, artifacts, inaccurate information, or unexpected results.
You are responsible for reviewing generated:
- code;
- meshes;
- materials;
- textures;
- animations;
- scripts;
- configuration changes;
- project modifications; and
- other outputs
before relying upon or distributing them.
Where the Software presents an approval or preview workflow before making a material change, you are responsible for reviewing the proposed change before approving it.
Exaro does not claim ownership of content merely because it was generated through the Software.
However, rights in AI-generated output may depend on:
- applicable law;
- the Third-Party Service used;
- that provider's terms;
- the Input used; and
- the nature of the resulting output.
Exaro does not guarantee that any particular AI-generated output is copyrightable, unique, non-infringing, or suitable for commercial use.
15. Your Content
As between you and Exaro, you retain your rights in Projects, prompts, source files, images, models, code, and other content you provide to or create with the Software, subject to any rights held by third parties.
You are responsible for ensuring that you have the necessary rights to material you provide to the Software or a connected Third-Party Service.
Use of Inputs and other information by Exaro is governed by the Terms of Service and Privacy Policy.
Use of content by a Third-Party Service is governed by that provider's applicable terms and policies.
16. Third-Party and Open-Source Components
The Software may contain third-party or open-source components.
Such components may be governed by separate license terms.
Where a third-party or open-source license requires notices, attribution, source availability, or other terms, those terms apply to the applicable component.
Nothing in this EULA is intended to restrict rights granted directly to you under an applicable open-source license. This includes your rights under the GNU General Public License in the Exaro Model Blender Extension (Schedule A, section A1).
Third-party license notices may be provided:
- with the Software;
- in documentation;
- in a NOTICES or LICENSES file; or
- through another reasonable location identified by Exaro.
17. Beta and Experimental Features
Exaro may make experimental, beta, preview, or pre-release features available.
Such functionality may:
- contain additional bugs;
- change without notice;
- be incomplete;
- produce unexpected results; or
- be discontinued.
Beta or experimental functionality should not be relied upon for critical production systems unless Exaro expressly states that it is production-ready.
Mandatory consumer rights remain unaffected.
18. Fees and Refunds
Fees, billing periods, and license duration are disclosed at or before purchase.
Exaro Unreal plans and the Exaro Studio bundle are subscriptions that renew automatically until you cancel, as set out in section 3. Paid Exaro Model plans are subscriptions that renew automatically until you cancel, as set out in Schedule A, section A2; Exaro Model Free is free of charge (section A15).
You may ask for a full refund of your first Exaro Unreal or Exaro Studio bundle payment within 14 days, no reason needed. A refund ends the subscription and revokes its License Key (section 11).
Refund eligibility is governed by the Exaro Studio Refund Policy and applicable law.
A valid full refund terminates the associated Software license.
Nothing in this Agreement limits refund, cancellation, conformity, or other consumer rights that cannot legally be waived.
19. Ownership
The Software is licensed, not sold.
As between you and Exaro, Exaro retains all right, title, and interest in the Software, including its:
- source code;
- object code;
- architecture;
- user interface;
- documentation;
- trademarks;
- branding; and
- other intellectual property,
except for components owned by third parties.
No rights are granted except those expressly stated in this Agreement.
20. Feedback
If you voluntarily provide suggestions, ideas, bug reports, or other feedback concerning Exaro, you grant Exaro permission to use that feedback to develop, improve, market, and operate its products without payment or other obligation to you.
This does not transfer ownership of your Projects or other unrelated content to Exaro.
21. Support
Support services, if any, are provided according to the plan or product description applicable to your license.
Exaro does not guarantee a particular response time or resolution time unless expressly stated in a separate service-level agreement.
You may be asked to provide logs, configuration information, Unreal Engine or Blender version information, or other diagnostic information reasonably necessary to investigate a technical problem.
22. Disclaimer of Warranties
To the maximum extent permitted by applicable law, the Software is provided "as is" and "as available."
Except for express representations made by Exaro, Exaro disclaims implied warranties including merchantability, fitness for a particular purpose, title, and non-infringement to the extent those warranties may legally be disclaimed.
Exaro does not warrant that:
- the Software will be error-free;
- the Software will operate without interruption;
- the Software will support every hardware or software configuration;
- every third-party integration will remain available;
- generated output will be correct or suitable for production;
- the Software will meet every user's particular requirements; or
- all Software versions will be maintained indefinitely.
Some jurisdictions do not permit certain warranty exclusions. In those jurisdictions, these exclusions apply only to the extent permitted by law.
23. Consumer Digital-Content Rights
Nothing in this Agreement excludes rights that cannot legally be waived.
In jurisdictions providing mandatory rights concerning digital content or software, you may be entitled to remedies if the Software is materially defective, not supplied, or does not conform to what was promised.
Depending on applicable law, remedies may include:
- correction or repair;
- replacement;
- a price reduction;
- termination; or
- refund.
This EULA will be interpreted consistently with such mandatory rights.
24. Limitation of Liability
To the maximum extent permitted by applicable law, Exaro and its owners, officers, employees, contractors, and affiliates will not be liable for indirect, incidental, special, exemplary, consequential, or punitive damages arising from or relating to the Software.
This includes, to the extent permitted by law:
- lost profits;
- lost revenue;
- lost data;
- loss of goodwill;
- business interruption;
- project delays; or
- costs of substitute products or services.
To the maximum extent permitted by law, Exaro's total aggregate liability arising from or relating to the Software or this Agreement will not exceed the greater of:
- the amount you paid to Exaro for the applicable Software during the twelve months preceding the event giving rise to the claim; or
- one hundred U.S. dollars ($100).
These limitations do not apply to liability that applicable law does not permit Exaro to exclude or limit.
25. Indemnification for Business Users
To the extent permitted by law, if you use the Software on behalf of a business or for commercial purposes, you agree to defend, indemnify, and hold harmless Exaro and its owners, officers, employees, contractors, and affiliates against third-party claims and reasonable expenses arising from:
- your unlawful use of the Software;
- your violation of this Agreement;
- your unauthorized redistribution of the Software;
- content you provide to the Software;
- your violation of another person's rights; or
- your misuse of a Third-Party Service.
This provision does not impose an indemnification obligation on a consumer where applicable law prohibits such an obligation.
26. Term and Termination
This Agreement begins when you accept it or first download, install, activate, or use the Software.
For Subscriptions, the license continues while your subscription is active and, for a version you keep under section 3, after it ends, unless terminated for material breach.
You may terminate this Agreement by discontinuing use of and uninstalling the Software.
If you materially breach this Agreement, Exaro may terminate your license as permitted by applicable law.
Where the breach is reasonably capable of cure, Exaro may provide notice and an opportunity to cure before termination when appropriate.
Upon termination of your Software license, you must stop using the applicable Software except for rights expressly stated to survive.
Existing Distributed Projects
Termination or expiration does not ordinarily require you or your customers to stop using completed Projects that were lawfully created and distributed while you held a valid license.
Authorized Runtime Components incorporated into those Projects may continue to operate and be distributed as part of those Projects.
However, this provision does not legitimize copies of Exaro Software that were distributed in violation of this Agreement.
Sections concerning ownership, restrictions, liability, existing distributed Projects, and other provisions that by their nature should survive termination will survive.
27. Export and Sanctions Compliance
You may not use, export, re-export, or transfer the Software in violation of applicable export-control, sanctions, or trade laws.
You are responsible for complying with laws applicable to your use and location.
28. Governing Law and Venue
This Agreement is governed by the laws of the Commonwealth of Virginia, United States, without regard to conflict-of-law principles.
Subject to mandatory consumer protections and jurisdictional rights that cannot legally be waived, disputes arising from this Agreement will be brought in the state or federal courts of the Commonwealth of Virginia.
Nothing in this provision deprives a consumer of mandatory protections provided by the laws of the consumer's place of residence.
29. Relationship With Other Exaro Terms
This EULA governs the Exaro Software.
Schedule A contains the product-specific terms for Exaro Model.
The Exaro Terms of Service govern your Exaro account, website use, purchases, and general use of the Services.
The Exaro Asset License governs marketplace Assets unless product-specific terms state otherwise.
The Acceptable Use Policy governs prohibited use of Exaro services and systems.
The Refund Policy governs refund eligibility.
The Privacy Policy explains how Exaro handles personal information.
If two agreements directly conflict:
- product-specific terms control for the specific product;
- this EULA controls regarding the Software;
- the Asset License controls regarding marketplace Assets; and
- the Terms of Service control regarding general website and account matters.
30. Changes to This Agreement
Exaro may update this Agreement from time to time.
Material changes will apply prospectively unless applicable law permits otherwise.
For a version you keep, Exaro will not materially reduce the core license rights previously granted solely by posting a new version of this Agreement.
For online services and subscriptions, updated terms may apply to future service or subscription periods after reasonable notice where required.
31. Assignment
You may not transfer this Agreement or your Software license except with Exaro's written permission or where applicable law gives you a non-waivable right to do so.
Exaro may assign this Agreement in connection with a merger, acquisition, corporate reorganization, or sale of substantially all relevant assets.
32. Severability
If any provision of this Agreement is determined to be invalid or unenforceable, the remaining provisions remain effective.
The affected provision will be enforced to the maximum extent permitted by law consistent with its intended purpose.
33. No Waiver
A failure by Exaro to enforce a provision of this Agreement does not waive Exaro's right to enforce that provision later.
34. Entire Agreement
This Agreement, together with terms expressly incorporated by reference, constitutes the agreement between you and Exaro regarding the Software and supersedes prior agreements concerning the same Software to the extent permitted by law.

Schedule A — Exaro Model
Product-specific terms · Last updated October 23, 2026
A1. The Product and Its Two Parts
Exaro Model is installed by one Windows installer and has two separately licensed parts:
- the Engine: the Exaro Studio engine companion application (
exaro-blender.exeand the files installed with it, including its pipelines, variant builder, retargeting, Unreal hand-off, MCP server, license check, and client for the Build Service), its documentation, and Updates to it. The Engine is proprietary and is "Software" under this Agreement; and - the Blender Extension: the add-on that runs inside Blender (extension id
exaro_studio_blender). The Blender Extension is free software licensed under the GNU General Public License, version 3 or (at your option) any later version (GPL-3.0-or-later), as stated in its own LICENSE file.
This Agreement does not apply to the Blender Extension and does not restrict any right the GPL gives you in it. You may use, study, modify, and redistribute the Blender Extension under the GPL whether or not you hold an Engine license. The GPL license in a copy of the Blender Extension grants no rights in the Engine. The Engine and the Blender Extension are separate programs that communicate over a local network socket on your computer.
Exaro Model is sold separately. An Exaro Studio license for Unreal Engine (Individual or Studio) does not include it, and a Exaro Model license does not include the Exaro Studio plugin for Unreal Engine. The Exaro Studio bundle includes both (section 3).
A2. Subscription, Renewal, and Cancellation
Exaro Model is sold as a subscription: Individual at US $29 per month or US $249 per year, or Studio at US $999 per year. The price that applies to you is the one shown at checkout. Your subscription includes the Updates released while it is active and use of the Build Service (section A5).
Exaro Model is also offered free of charge as Exaro Model Free, on the terms in section A15. Sections A2 to A4, A8 and A13 apply to paid subscriptions, not to Exaro Model Free.
Your subscription renews automatically at the end of each monthly or yearly period, and your payment method is charged the then-current price, until you cancel. You can cancel at any time, in a few clicks, from the account page on exarostudio.com; you do not need to contact us. Cancelling stops the next renewal. You keep access until the end of the period you have already paid for, and we do not refund the rest of that period except as section A13 or the law requires. Before a yearly subscription renews, we email you a reminder 15 to 45 days before it renews with the date and the price. We tell you at least 30 days before a price change applies to you, and you can cancel before it does.
A3. The Version You Keep After 12 Paid Months
Once you have paid for 12 months of Exaro Model in total (for example 12 monthly payments, or one yearly payment), you may keep using the version of the Engine that is current at that time, without further payment, for as long as you comply with this Agreement, even after your subscription ends. Each further 12 paid months moves the version you keep to the version current at that time.
A kept version gives you its local features only (section A5): the Blender Extension, viewport preview, the basic modelling techniques, renders, and export. It does not include the Build Service or later Updates. Months that were refunded or charged back do not count.
A4. Seats and Devices
An Individual Exaro Model subscription is for one person (one Seat), who may activate the Engine on up to two (2) devices at a time; its License Key starts with EXAROBLENDER. A Studio subscription covers up to five users, who together may activate the Engine on up to ten devices; its License Key starts with EXAROBSTU. To move a license, deactivate an old device (exaro-blender licence deactivate) or reset your devices from your exarostudio.com account.
As in section 4, a company, organization, or team must use Studio subscriptions; an Individual subscription may not be bought or used by a business entity for its employees or contractors. An Exaro Studio for Unreal Engine key does not unlock Exaro Model, and the reverse is also true; an Exaro Studio bundle key unlocks both (section 3).
A5. Local Features and the Build Service
The Engine's licensed features (building, rigging, animating and exporting) run with an active paid subscription, with Exaro Model Free (section A15, within its limits), or, for local features only, with a version you keep (section A3). Without any of these, they do not run; the Blender Extension remains yours under the GPL.
Local features run on your computer: the Blender Extension, preview, the basic modelling techniques, renders, and export. Connected features run on Exaro's Build Service (build.exarostudio.com): building with kits, model checks and the fixes they suggest, recipes, and learned updates to them. Connected features need an active subscription or Exaro Model Free and an internet connection while you use them. They do not work offline. The documentation lists which features are which; that split may change with Updates.
The Build Service is part of the Software, not a Third-Party Service. Its kits, checks and recipes stay on Exaro's servers; you may use the results returned for your builds in your work (section A11), but you may not use the service to extract or rebuild them, query it by automated means beyond your own building (scraping, systematic sweeps of parameters), or use its results to train or tune a model or build a competing service. If Exaro reasonably believes an account is doing so, it may limit, suspend or alter the service's responses for that account without notice. Each paid subscription has fair-use limits, shown in your account and set for heavy professional use (Exaro Model Free has the quotas in section A15); past a limit, requests may slow or pause until the next period, and you are never charged extra without your agreement. Exaro aims to keep the Build Service available but does not guarantee it will be uninterrupted; local features keep working when it is not. Beta features are offered only to paid subscribers who opt in to them.
A6. Activation and License Verification
You activate a License Key once, online. When you activate or refresh, the Engine sends Exaro's license server (api.codehawke.com) your License Key, a device identifier (a one-way hash computed on your computer from your Windows installation ID, the computer's name and your Windows user name; none of these is sent) and the Engine's version number. As with any internet connection, the server also receives your IP address.
The Engine refreshes the license about once a day when it can. Under a paid subscription or a kept version, local features keep working offline for at least 30 days after the last successful refresh (Exaro Model Free does not work offline; section A15); connected features never work offline. If a subscription ends, is refunded or charged back, or a Seat is removed, the Build Service refuses the key straight away and other licensed features stop at the next refresh, except the local features of a version you keep (section A3). Sections 10 and 11 also apply.
A7. Build Data
Build Data is what the Engine sends the Build Service when you use connected features: your briefs and plans, the measurements the model checks need, check results, the fixes offered, build outcomes, and what you asked to build and your feedback on results as your AI client passes them to the Engine's tools. A step that runs on the Build Service, such as rigging a creature or fitting clothing, also receives the mesh geometry (vertices, faces and weights) it works on; that geometry is used only to answer the request and is never stored. Build Data never includes your full AI conversations, textures, renders, reference images, Blender scenes or .blend files.
Individual and Exaro Model Free: Exaro keeps logs of requests to its service and its responses (the Build Data above), including what you asked to build and your feedback on results as your AI client passes them to the Engine's tools, never mesh geometry, to run and improve the service, including Exaro Model's kits, checks, fixes and recipes. These logs are part of how these plans are provided and part of these terms: you accept them when you subscribe to Individual or start Exaro Model Free, and the sign-up page says so before you start; they cannot be switched off on these plans. Exaro never sells Build Data and never gives another customer your specific design. Improvements Exaro makes belong to Exaro. Exaro keeps these logs indefinitely, stored under a pseudonymous account identifier, and does not delete them. If you close your account, Exaro deletes or anonymises its personal details (such as your email address and name; billing records are kept as the law requires), which unlinks you from the logs, as the Privacy Policy describes.
Studio: Build Data is processed only to answer each request and is not stored or used to improve anything. Exaro keeps only aggregate counts, such as the number of requests and which checks passed or failed, with no plans or content in them.
The Privacy Policy explains how personal information is handled.
A8. If the Build Service Ends
If Exaro decides to stop operating the Build Service permanently, it will give subscribers at least 90 days notice by email and on exarostudio.com and, before it stops, release a final version of the Engine that builds offline, without the Build Service. That version receives no further Updates. If the license server also closes, Exaro will first release an Update so that local features no longer need a license refresh.
A9. AI Clients and the MCP Server
The Engine runs an MCP (Model Context Protocol) server on your computer so that AI clients and models you choose, whether hosted frontier models or models you run locally, can operate it.
The AI clients and models are your own. Exaro does not provide, host, resell, or proxy any AI model or client, and no AI usage is included in the price. Your prompts and conversations pass between you, your AI client, and its provider under their terms; the Engine does not send your full conversations to Exaro. What your AI client passes to the Engine's tools when you use connected features, such as a plan, what you asked to build or your feedback on a result, becomes Build Data (section A7).
The Engine also includes optional tools that, when you or your AI client use them, connect directly from your computer to third-party asset libraries and 3D-generation services (Poly Haven, Poly Pizza, Sketchfab, Hyper3D Rodin, Tencent Hunyuan3D, and the CMU Graphics Lab Motion Capture Database), using account credentials you supply where the service requires them. What you send to those services goes to them, not to Exaro, under their terms, and content you obtain from them stays under its own license. Local review pages the Engine writes load a 3D viewer script from Google's public CDN.
Sections 13 and 14 apply to all of the above.
A10. Supported Configurations and Unreal Engine
Exaro Model requires Blender 5.2 on Windows 10 or Windows 11 (64-bit). Retargeting and import into Unreal Engine require Unreal Engine 5.5 through 5.8. Blender and Unreal Engine are obtained separately under their own licenses and are not included.
Sending a character into Unreal Engine delivers it to a running Unreal Editor that has the Exaro Studio plugin for Unreal Engine enabled. That plugin is a separate product under its own license and is not included with Exaro Model. Send to Unreal requires a paid Exaro Studio for Unreal Engine license in that Editor; the plugin's free tier does not include it.
Section 12 applies.
A11. Your Work, Your Files, and Your Inputs
As between you and Exaro, the models, characters, rigs, animations, and other output you make with Exaro Model are yours. Exaro claims no ownership of them and never sells, lists or redistributes them. Under a paid subscription or a version you keep, you may use them in commercial and non-commercial Projects. Output you make with Exaro Model Free is licensed for non-commercial use only (section A15(f)), including after you upgrade; work you build or export again under a paid subscription is not limited this way. The Engine never uploads your .blend files, and Exaro never sells .blend files.
Material you bring stays under its own license: models you bought or downloaded, content from Epic Games, output from AI generators, motion capture, and anything else you import. Output made from that material may remain subject to those licenses. You are responsible for having the rights to use it, and for complying with its terms.
Exaro Model does not include any Epic Games content. Where you retarget from Unreal Engine animation libraries (for example the UE5 mannequin or Epic's Game Animation Sample), the Engine reads that content from your own Unreal Engine installation and Fab library, and your use of it is governed by Epic's terms, which may limit how that content and work made from it may be used.
The human body generator uses the MakeHuman community's base mesh and morph targets, which are released under CC0 1.0 Universal. MakeHuman's program code is not used. We credit the MakeHuman community with thanks.
Section 15 applies.
A12. Open-Source and Third-Party Components
The Engine includes a Python runtime and open-source packages, each under its own license. They are listed in THIRD_PARTY_NOTICES.md, which is installed with the product. Section 16 applies.
A13. Refunds
Refund eligibility is governed by the Refund Policy and applicable law. You may ask for a full refund of your first Exaro Model payment within 14 days, no reason needed. A refund ends the subscription and revokes its License Key (section A6).
A14. How the General Sections Apply
Sections 1 to 36 apply to the Engine as Software, with these differences:
- sections A2 to A4 apply in place of the subscription terms and license tiers in sections 3 and 4; for Exaro Model, a version you keep in sections 1 to 36 means only a version you keep under section A3;
- section 3's exclusion of hosted services does not apply to the Build Service while your subscription is active (section A5);
- Exaro designates no part of the Engine as a Runtime Component, so section 6 does not permit you to distribute the Engine or any part of it. The output you make is not a Runtime Component; section A11 governs it;
- the Engine is provided in compiled form. Section 8 does not apply to the Blender Extension, whose source code you receive under the GPL; and
- sections 9 and 26 restrict and terminate rights in the Engine only, never your rights in the Blender Extension under the GPL.
Where this Schedule conflicts with sections 1 to 36 on Exaro Model, this Schedule controls.
A15. Exaro Model Free
Exaro Model Free is a free license to the Engine. These terms apply to it in addition to the rest of this Schedule; where they differ, this section controls for Exaro Model Free.
- No fee. You pay nothing and give no payment details. Because nothing is paid, section A13 (refunds) does not apply, and section A3 (a version you keep) never applies: Exaro Model Free has no fallback version.
- Who may use it. One person aged 18 or older, for their own use, with an exarostudio.com account and a verified email address. One Exaro Model Free license per person and per device; it may be activated on one device at a time. It may not be used by or for a business, company or other organization, or for paid work, and may not be bought, shared or transferred.
- Quotas. Connected features run within the quotas shown on the pricing page and in your account; when this version was published they were 10 builds a day and 150 a month; 3 game-ready exports a day and 30 a month, at one level of detail and up to 2K textures; and 3 humanoid rigs a day, with every construction kit Exaro has released. Sending to Unreal Engine or Unity, multiple levels of detail, 4K textures, commercial use and offline use are not included; they need a paid subscription.
- Online only. Exaro Model Free needs an internet connection. Its license expires 24 hours after each refresh and the Engine refreshes it while you are online; without a successful refresh, its licensed features stop until you reconnect. The offline period in section A6 does not apply.
- It may change or end. Exaro may change Exaro Model Free's quotas, kits, features or these terms, or stop offering it, at any time, and will say so on exarostudio.com and, where practical, by email beforehand. Section A8 does not apply. There is no service level and no guarantee of availability; support is community support only. Sections 22 to 24 apply.
- Non-commercial output. As between you and Exaro, what you make with Exaro Model Free is yours, but you may use it for non-commercial purposes only: learning, personal and hobby projects, evaluation, and showing it in a portfolio or online without charge. You may not sell or license it, list it on any marketplace, use it in a product, game or service that is sold or monetized, or use it in work for a client or employer. This limit applies to output made while you used Exaro Model Free, also after you upgrade; work you build or export again under a paid subscription is not limited by it. Section A11 otherwise applies.
- Request logs. Exaro keeps logs of Exaro Model Free's requests to its server and the responses, to run and improve the service, as for Individual (section A7), and keeps them as section A7 describes.
- Fair play. Creating more than one free account, sharing a key, getting around the quotas or device limit, automating sign-ups, or giving a false age breaks these terms, and Exaro may refuse, suspend or revoke the license without notice. To enforce this, Exaro keeps your account, the device identifier described in section A6 and a one-way hash of the IP address you signed up from, as the Privacy Policy describes.
- Upgrading. When you take out a paid Exaro Model subscription, it replaces your Exaro Model Free license: the free License Key is revoked and its device deactivated, and you use the paid key instead.
