Bronze Field Cannon with Firing Effects

A 6-pounder field gun of the black-powder era, the kind that defended forts and missions on the frontier and in the Texas Revolution (the Alamo's walls carried guns like it).

The cast bronze barrel has its cascabel, base ring, reinforce and chase rings, muzzle swell, vent field and two dolphins, and a real open 9.4 cm bore 1.85 m deep, so a crewman's sponge-rammer goes down it to the charge. The trunnions sit under iron cap squares on a two-cheek bracket-trail carriage with transoms, an elevating screw, an iron trail plate and a ring for the handspike, on two spoked wooden wheels with iron tyres.

Rigged with two clips: Fire (the gun recoils 0.6 m back along its trail, the wheels turning) and RunUp (back into battery). Sockets: muzzle (spawn the flash and smoke here, +X along the bore in the effect frame), vent (the priming flash) and trail_ring_socket (the handspike). Included: three sprite flipbooks rendered from smoke and fire simulations, each with colour, normal and motion-vector atlases and a sidecar describing the grid and timing: CannonSmoke (a thick white-grey cloud that billows and lingers), CannonFlash and CannonVentPuff.

The muzzle, vent and trail ring sit where a standard gun-drill crew stands to them: muzzle face 1.3 m ahead of the axle and 1.0 m up, vent 0.55 m behind it, trail ring 2.1 m behind.

22,000 triangles, one PBR material (2048 px colour and normal maps; the GLB also carries its roughness map), real-world scale with its origin on the ground under the axle, muzzle facing -Y. FBX for Unreal and Unity and GLB for Godot, three.js and glTF importers, with PNG textures.
