The settings for generating and receiving global illumination are on the Object Properties dialog mental ray Panel (Object Properties Rollout).

Which renderable objects can receive global illumination.Which renderable objects can generate global illumination.Which light objects can generate global illumination.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)). I invest a lot of time in keeping the code up to date and compiling everything, so any financial help would be appreciated.Note: In order to use global illumination in mental ray, the photons must be able to bounce among two or more surfaces. If anything doesn't work as expected, let me know and I'll see if I can fix it.Īlso, if these plugins are in any way useful to you, please consider making a donation using the Paypal button on the left.

Other than checking to see if they load properly, nothing has been tested. I have recompiled a huge amount of plugins for Max 2024.
