If you are rendering a scene with final gather and the lighting flickers, follow these steps:
- Enable the option under the section, Final Gathering Tracing subsection in the Indirect Lighting tab of the Render Settings: mental ray tabs. The option sets the final gather mode to multiframe.
See Render Settings: mental ray tabs for more information.
- Set the Render Mode to render final gather maps using this command:
setAttr mentalrayGlobals.renderMode 3;
- Set the scene to render a representative subset of frames or a coarse version of the animation.
- Set to under the section of the Indirect Lighting tab of the Render Settings: mental ray tabs.
- Set Render Mode to full render using this command:
setAttr mentalrayGlobals.renderMode 0;
- Fully render the scene.
Note
While this workflow avoids flicker, some parts of the scene may still suffer in quality if an insufficient number of final
gather points is found.
