Shading issue + grained texture

[kayvenn7]

Hello! With "Use Amplify Shaders" on, characters have strange object space shading, as well as grained texture artifacts. It seems this issue is only with skin materials/shaders.

Turning off amplify shaders solves the issue, but it would be nice to be able to use amplify shaders :)
