In the last two days the rocks got some base coloring and textures (Ambient Occlusion and Dirty Vertex Painting). I tried to pick some colors from the reference picture. While painting I noticed that unfortunately nearly all of them have some shading artifacts. I’m sure that is a result of a bad retopo. Don’t know how to fix it at this stage. The good thing is, that you only can see the artifacts if you come really close. So maybe that is not so bad.
