This page provides information about the caustics render channel in V-Ray for Blender.
Overview
Caustics is an effect that is produced when light rays are reflected or refracted by the materials within a scene, which can produce light patterns on objects in the scene. The Caustics Render Channel displays these effects, generated with Caustics photon mapping. It is enabled from the Caustics Rollout rollout under the GI tab in the Render Settings window. This render channel is useful for enhancing or toning down caustic effects in the composite.
