I Googled like mad for the reflection coefficients of gold at various angles. I could not find it.
So I've spent all week photographing gold in very careful ways and measuring the colors. (Also copper, brass, and a few others.)
Then I built a shader. Here it is demonstrated.
Gold is 255, 215, 147 when viewed straight on. It changes in surprising ways as the viewing angle becomes more shallow.
Click the pic for bigger.
PS: I know my shadow doesn't match the environment - I was just trying to anchor the piece on the ground so it would not be floaty/distracting.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
