In this tutorial you will learn how to create gold, silver, and copper material. Key terms include reflection, specular, index of refraction, fresnel, and fall-off. This tutorial is aimed at both beginners and professionals. Although this tutorial is based on 3D Studio Max, the same settings (such as the RGB color values) apply to many other 3D products.
In my search for gold material and other metals such as silver and copper, I noticed there are a lot of different opinions on how to create them. There is probably some truth in most of them, but since many of those opinions conflict, they can’t all be right. I’m not saying I’m right either, I’m probably not actually because there is always room for improvement. I’ve read several boring papers and done about 40 test renders (that takes about two eternities on my PC) before I got acceptable results. Let’s just say that the examples below work for me and with or without a little tweaking they might work for you too.
If you don’t feel like going thru all the steps in this tutorial, you can download a matlib (.mat) file for 3D Studio Max thru a link at the bottom of this tutorial.
