If
you are rendering a scene with final gather and the lighting flickers,
follow these steps:
- Enable the Optimize for Animations option
under the Final Gathering Tracing section,
Final Gathering Tracing subsection in the
Indirect Lighting tab of
the
Render Settings: mental ray tabs.
The Optimize for Animations option
sets the final gather mode to multiframe.
See Final Gathering Modes
in the mental ray for Maya reference guide 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 Rebuild to Freeze under
the Final Gathering Map 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.
NoteWhile this workflow
avoids flicker, some parts of the scene may still suffer in quality
if an insufficient number of final gather points is found.
