Patreon Tutorial #34 - Part #18 - Using OSL - FakeCaustics (Patreon)

In this tutorial I will be going over the FakeCaustics OSL node. This node generates a "caustic" like procedural noise pattern. This can be useful for psuedo fake caustics on surfaces if you just need a simple and fast to render illusion of caustics. Normally Caustics can be very slow and heavy to render so this is a way to fake it with very little overhead on the render times. This effect can be used as an overlay on surfaces and animated to give it a subtle movement. Pretty useful node for saving render time and being a procedural noise pattern it could also be used for general shading purposes also.
