This is a model of the M1841 Cannon used in the Spanish American War and the Civil War. It fires a 6lb Cannonball. I have animated the cannonball firing and also baked in a smoke simulation. The model uses 4K photorealistic textures. This was made in Blender3D using Cycles.
***Unfortunately the smoke domains dont work in Sketchfab, so there is only the animation in this preview.***
