I created a sculpt, then retopologyzed it via Poly Build Tool and Shrinkwrap-Modifier. Now I'm trying to bake a normal map for the low-poly object but its really not looking like it should. The normal map looks ok to me, but every island of the uv-mesh looks totally diffrent in viewport and render. It looks to me a little like the normals were partially flipped, but I already recalculated them. So that should not be the problem, I guess. Maybe it is a Blender 2.8 problem. What do you think?
Thank you for your time! :)
