Thanks for the response.
I’ve actually done this for another game, I got the UVs then with that could get the pixel coordinates on the texture and then with that I could get the color from a texture.
However, in this case I’m not sure how I can get the opacity of a material? I have no texture to reference in this case. I’ll have to think about that.
They definitely do it with the editor somehow, and I’m digging through the source to see how they do it but admitly don’t known where to look precisely.
