VRay Interior Lighting & Rendering Tutorial. Vray for 3d Studio Max Tutorials | Vray Basic Render Settings. Caustics are light patterns formed by refracted/reflected light. Take a look at the rendered image, these are caustics. There are two types of caustics: GI caustics and direct light caustics. In the GI rollout, you may have noticed two check-boxes: reflected and refracted GI caustics.

GI caustics are created by GI light (=bounced light). In fact, if you want the GI light to pass trough transparent objects, you MUST enable refracted GI caustics. If not, transparent objects will cast a solid shadow. These caustics are computed by the GI engines, and can therefore be quite slow and not very detailed. Also, if you have for example a max omni or directional light in your scene, they will not generate caustics as it is not GI light.

But, if you want caustics from max lights, or very sharp detailed caustics, you have to enable the Vray direct light caustics (also called photon mapped caustics). Seamless, Tiling Textures.
