This page gives some basic details about the Raw Refraction Filter Render Element and how it is used in compositing.



The Raw Refraction Filter Render Element is similar to the Refraction Filter Render Element, except it is not affected by the reflection weight. The result is a solid mask showing the pure refraction color as set in the V-Ray Material's settings.
