This is a simple material study I did after being inspired by Reynante’s work. I hope you like them, and if you have any suggestions I would welcome feedback.
Also, these are not all my idea, I’ve borrowed and tweaked other shaders as well as created completely original ones.
And here are the node setups:
Diamond (the saturation is set to 1 and the value is set to 0.6 on the diamond colors):
You will need to tweak the displacement scale and amount depending on how you use it. Also, the water shader is clear when it is a smaller amount.
I hope you like them.
