alternate method on page 6113 . Increasing the value increases the smoothness
of the result, and the required number of calculations, hence the render time
(but not as much as you might expect).
This setting is unavailable when
Use Radius Interpolation Method on page
6113 is enabled.
Diffuse Bounces Sets the number of times mental ray calculates diffuse light
bounces for each diffuse ray. Default=0.
Like Maximum Reflections and Maximum Refractions, this value is subject to
the restriction of Max Depth. If you set Diffuse Bounces higher than Max
Depth, the latter setting is automatically raised to the Diffuse Bounces value
in the MI output file, but this is not reflected in the 3ds Max interface.
NOTE When Global Illumination on page 6100 is on, changing this setting has no
effect.
Weight Controls the relative contribution of the diffuse bounces to the final
gather solution. The value scales from "using no diffuse bounces" (value=0.0)
to "use full diffuse bounces" (value=1.0). Default=1.0.
Final Gather Map group
These controls tell mental ray how to calculate the final gather map for indirect
illumination. The map uses the
FGM file format on page 7775 .
Read/Write File When on, the mental ray renderer saves the final gather
map to the specified FGM file, if it doesn't already exist. If the file exists, mental
ray loads it and uses the map data it contains instead of generating a new one.
Read Only (FG Freeze) Determines whether or not mental ray uses the final
gather map file as is. When off, mental ray can add new final gather points if
necessary. When on, mental ray uses only the data in the specified file, and
does not generate any new final gather points during the pre-processing stage.
It can still generate new final gather points while rendering when using the
radius method. Available only when you've specified an FGM file. Default=off.
... [Browse] Click to display a file selector dialog, which lets you specify a
name for the final gather map (FGM) file, and the folder where it is saved.
[file name] When you have used the Save button to specify a final gather
map file, the name field displays its name and path.
Delete File Click to delete the current FGM file.
