You want to keep your polycount as low as possible! If the edge loops and the desired wrinkles are not exactly at the same position, the mesh will deform not correctly, exposing the faces and creating artifacts.įirt pragmatical fix, most of the people come up with "just increase the polycount until i see no more artifacts. Logically real skin does not have any polygons, meaning it bends right where the muscle is.īut in 3D we have polygons and this is a problem.
In real world skin behaves like a tight layer that gets stretched by the muscles and bones right beneath it. But i try to give a rough overview that may serve as a general guideline for further investigation.
