I have this dark artifacts on parts of the meshes when they intersect each other, the parts are just joined, not boolean together, this happens when I use subsurface effect in my shading properties of material. When I use boolean, it disappears. Is there a way to avoid having those dark spots, without welding the mesh together with boolean?
Cheers, Piotrek
The problem is gone after using boolean, but i would like not to use it
