Hi All, I'm new to 3D coat and still trying to learn my way around. I have a high resolution mesh which I sculpted previously in Sculptris and I already have a low poly retopology that I wish to bake to (after painting). So I imported the mesh, and it's in Surface mode. Under Retopo, I import the low res mesh. After painting the hi-res, if I bake, the textures work fine, displacement, etc, but my normal map is just entirely gray. Does the mesh need to be voxelized before baking? Thanks!
