How to create photorealistic gold with V-Ray and 3DS Max

There has been a lot of talk in various forums over the years in how to accurately render realistic gold. Some of it used to get quite heated with different opinions and demands on even the smallest of detail.
However, with the tools we have today we can render gold in a fraction of the time it used to take. The reason is simply that with a falloff set correctly or with more modern OSL (Open Shading Language) you can, along with other settings, know that you are creating scientifcally accurate gold.
In this tutorial I will show you how.

thank you so much for the first time my gold rendering came well...this is the best video on gold rendering

[@leonleon51]

Most welcome 😊

Wow! Scientific 3DsMax!

Most realistic gold shader for v-ray I have ever seen :)

Where can we find the n values for the red/green/blue wavelengths for other metals e.g. chopper?!

[@leonleon51]

Same place as the gold. Go to refractiveindex.info/?shelf=3d&book=metals&page=aluminium and then change the page from aluminium to which ever metal you need. :)

​@@leonleon51 What I mean, the input wavelength for Au we use is 0.65 0.55 0.45 as mentioned in Chaos OSL, so we use the same wavelengths for other metals, or should be different and where to find? (Btw, thank you for the awesome tutorial!!!)

Thank you sir for this lesson!!

[@MrArturo82]

Thanks for very useful lesson. Could you make photorealistic diamonds material lesson?

[@leonleon51]

Sure, I can do that.
