Hi! You need create a point position mask, try to use aiUtility node with flat color and shadingPoint mode, after that connect aiUtility R or B channel to V coordinate you ramp, it will be work with object position not a uv.
Thank you for the help. And when you say I need to create a point position mask, how would I do that? Is it an actual map or is it from the aiUtility connected to the ramp?
Here's what I have. I don't understand why the two ramps are different sizes on each eye.
Hi! You create mask with a Utility.
Different sizes, I think you have different scale in geometry, try to symmetrise eyes and not combine them to one shape
