There is no engine-specific project included, but the GLB and OBJ exports plus the separate PBR maps import into both without trouble. Use the metal-rough workflow and set the normal map to OpenGL (Y+); Unreal expects DirectX (Y−), so flip the green channel there.

Yes. They are packed into the .blend and additionally supplied in a textures folder as 4K PNG and JPEG, so you can use them outside Blender.

Yes. The product is Royalty Free – you can use it in commercial work, games, films and client projects. You may not resell or redistribute the model itself as a standalone asset.

Yes. Each caster is a separate object with its origin placed at the swivel axis, so you can rotate or animate them without moving anything else.

No. The lid is modeled closed as a separate part. You can detach and rotate it yourself, but the interior is not modeled and there is no rig or animation.

It is built for realtime use: one material, one texture set, non-overlapping UVs and baked high-poly detail instead of modeled geometry. It comes in at around 77,000 triangles, which is comfortable for hero props and mid-ground objects but not a tiny background asset. There are no LODs included.
