And because the mesh only serves as an icon, I only needed to create 2 textures, one for each side visible to the camera.

Thanks! I used the worn and detailed ammo icons from Stalker 2 as reference.

First I created the shotgun shells, and I designed it in a way to where I would easily replace icons for other types of ammo, simplifying the texturing process.

Nice. Is it a static background or are things moving?

Thanks!
