I have a character in a scene and I would like to know the colors illuminating each side of their face. I’m guessing it might be an illumination or a shader thing? Any help welcome.
Hey
I found this nice explanation, which should give a good idea of how it works How to get pixel color using raycast on object with Lightmap created by "Beast"? - Questions & Answers - Unity Discussions
We don’t use Beast for baking lightmaps anymore, but I checked most of the other API points and they seem to still be around. The main concept should be the same.
Let me know how it works out 
Ah interesting, thanks. I ended using this mechanism which is similar just a different way of capturing the texture Script to calculate resulting surface color - Unity Engine - Unity Discussions
