my last question was too difficult so this hopefully this will be easier to answer :p
Is there a way to use a camera view or location data to determine whether or not a color/texture appears?
I plan to use a node equation that takes a blue color channel, and the higher the blue value, the easier the texture would show.
My end result would be looking like this, except the bright areas would be moved my the camera/view, rather than light rotation.
The setup is easy to replicate so I don't see the need for a .blend file, you could just texture paint certain parts of a sphere or cube blue to get the same result.
I hope this isn't too complicated since I have a tendency to ramble in my questions, I'd be grateful for any help!
