Hello! I’m working on an eye shader and have a question. I want to invert where the lighting on the iris (The bumpy red ring) is, from top to bottom.
In this image, the lighting is at the top.
But I want it to be at the bottom. How do I do this with materials? I’m assuming it has something to do with the light path node.
Here’s my shader setup.
Also, the light at the top is from a sun lamp.
