Newbie here with possible strange request.
I am learning anatomy, currently by studying a 3d skull. I would like to lit it in some ways, so that the faces facing front would be in a certain color, the faces facing left in another, the faces facing right in another.. you get the idea. This would come with some threshold i guess: lit faces that are x degrees facing front for example.
I guess that i would have to dig into creating a shader to do so? Maybe with the normals? Maybe what i want is not possible?
Thanks in advance! Y
