Store and reuse Final Gather results
 
 
 

By default, mental ray for Maya ignores any previously generated final gather results each time final Gather render happens; final gather results are freshly calculated.

You can store final gather results so that later frames can use the results from a frame rendered earlier to speed up the Final Gather rendering process.

Store and reuse final gather results when you aren’t going to be changing any final gather settings between renders (for example, when rendering a still image). You may be able to reuse a final gather map for animation, as long as the irradiance values for moving objects don't change significantly.

By default the file is saved into the current project's mentalRay\finalgMap directory.

NoteYou cannot reuse Final Gather results if you change final gather settings. In this case, the following Output window messages indicate that the previous results can’t be used:
