Bake a Deep Grid
I'm in doubt if will be possible to bake a 3D grid with deep z depth into a texture map, so to apply it as a material. The goal is to reproduce this kind of self-porting grid used in the step of a staircase.
I can model it in some DCC system, but being a 3d model I don't know if I can transform it in just a material to be applied on a solid rectangle or better I just use the the 3d model itself.
Maybe a not so clear explanation, the topic it's not clear to me also.
