By default, all objects in 3ds Max are set to generate and receive global illumination. The settings for generating and receiving global illumination are on the Object Properties dialog mental ray Panel (Object Properties Rollout).

Which light objects can generate global illumination. nvidia mental ray NVIDIA will no longer offer new subscriptions to the Mental Ray plugins for Maya and 3ds Max, as well as Mental Ray Standalone from Novemonward.You enable global illumination on the Render Setup dialog Indirect Illumination panel Caustics And Global Illumination rollout, and final gathering on the Final Gather rollout. You can reduce or eliminate these artifacts by turning on final gathering, which increases the number of rays used to calculate global illumination. Using a photon map can cause rendering artifacts such as dark corners and low-frequency variations in the lighting.
Otherwise you’ll receive error messages and no photons will be stored. This can be accomplished by having a single object with some concavity in its surface that’s exposed to the light source, or at least two objects, and at least one object must be set to receive global illumination (see mental ray Panel (Object Properties Rollout)). Note: In order to use global illumination in mental ray, the photons must be able to bounce among two or more surfaces.
