Method

The RT Glass Refraction node is a fast cheap raytraced glass solution.

This node can be used in scenes that need additional performance such as lightmapped scenes that aren’t using the pathtracer node.

Once the Glass Refraction node is added to the scene, (making sure that Raytracing is enabled on the root) this will enable you to simulate glass materials such as bottles, windows and glass on any raytraced enabled RT glass or transparent material/surface.
