Bagginsbill, I gave your suggested base color some test renders and it seems to give a good representation of 18K gold. I was shooting for an equivalent shade to what SM released in their P11 content as "Superfly Basics". In that regard, it was a match, but it is certainly too "yellow" IMO to be physically accurate, more toward 24K if anything. That said, given your example, I have incentive to play with the GlossyBsdf/FresnelBlend combination now. The ultimate goal of course is to be familiar enough with each type of node to use them "semi" effectively. From there, I hope I can grow into creating some more useful and versatile materials for SF renders, or at least have fun in the process. ;) Best Regards, Jerry

You're quite correct - the RGB value I suggest is the result not of Googling, but my own research and measurements with my own wedding ring, which is indeed 18K gold.

If you like a richer gold look try less blue, such as RGB 255, 215, 100. Generally speaking the hue of gold, resulting from red 255, green 215 is exactly correct. The saturation (affected by the weakest component, blue) is variable and in real life is affected by the amount of "white" metal mixed in with the gold.

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)
