I saw your works on CGsociety. I envy you. How do you get so good? Do you have powerful computer? Does your computer ever crashes or freezes?

Here is the layer shader. All I want to know how to render caustic in layer?

It will not show caustic on dice that has been textured. The dice has very complex shader linking that prevents from displaying caustic. Here is one with caustic without the dots.

Can someone tells how to use caustic in render layer?
