In looking at statistics for this blog, I have noticed that one of the most searched for items is "Vray Caustics."  That being the case, I thought I would post this simple and easy tutorial that goes over just that.  This tutorial will show you how to easily create caustics in Vray, and the render time is minimal.  Bertrand Benoit did some tests, and came up with these two images that show the effect this technique can have.
