Hi I can’t use a mix shader on Mac. Its High Sierra 10.13.6, Radeon RX 580 8gb, Blender 2.83.3
Each principled shader looks fine. When I combine them with a mix shader it gets all weird looking.
One shader is for the skin, the other is for the inside of the mouth. I am using backfiring plugged into a mix shader to make the inside of the mouth have a different look. This setup works great on my Win10 machines. I discovered this when trying to render an animation and one of my nodes is a mac pro.
