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 the same object or on other objects. The Caustics Render Element stores the effects that are generated with Caustics photon mapping, enabled from the Caustics rollout under the GI tab in the Render Setup window. This render element is useful for enhancing or toning down caustic effects in the composite.
