Learn how to achieve a caustics effect using a node shader.

Just completed a video description of a material that will allow fast fake caustics in Cycles. It’s especially useful for those interested in having a caustic effect that looks visually pleasing but aren’t so interested in the super long render times required for true caustics in a path tracer. Anyway, hopefully it can be of some use to someone out there. Hope you all enjoy!

great job, love fast work arounds
Cycles is showing its power more and more. There are so many good ways to do spectacular things, both by physically accurate methods and the old reliable quick workarounds. And even the shortcut methods make stunning results easy to achieve!
