What do you think about that? At the moment they are separated objects (holder and edge) but they are on the same map (4096 x 512) for each set, PBR materials.
I think it’s all for now, so edges and handles are separated now and contains separated uv space and textures - 2048x1024 for each, PBR - specular set up (albedo, spec, normal, AO).
So here you may have actually 64 knifes (if I count them right).
I’m going to give 1 for free
