When on, this toggle also tells the mental ray renderer to save frames as
temporary .map files. This allows you to render extremely large frames without
running out of random-access memory.
The location of the temporary map files is chosen in the following order:
1 If the file \[program folder]\mentalray\rayrc contains a registry entry called
_MI_REG_FBDIR, the renderer uses this directory.
The entry should have the form
registry "{_MI_REG_FBDIR}" value "<path>" end registry
where <path> is the directory you want to use.
2 If the rayrc file has no registry entry, the renderer uses the directory
specified by the TMPDIR environment variable.
3 If there is no TMPDIR environment variable, the renderer uses the
directory specified by the TEMP environment variable.
Material Override group
Material Override allows you to render a scene with all its materials replaced
by a single master material. For example, if you need to do a wireframe pass,
you can create a Wire material and then specify it here. When you render, all
surfaces will use the Wire material.
Enable When on, rendering uses the override material for all surfaces. When
off, surfaces are rendered with the material applied to them in the scene.
Default=off.
Material Click to display the Material/Map Browser on page 5194 and choose
a material to use as the override. Once you have chosen an override material,
this button displays the material name.
Export to .mi File group
These controls let you save the translated scene in a mental ray
MI file on
page 7848 . Before exporting, you must specify an export file by clicking the
ellipsis [...] button.
NOTE Exporting to an MI file is not available when you render to texture on page
6169 .
Export on Render When on, saves the translated file to an MI file instead of
rendering when you click Render. Available only after you have clicked the
ellipsis [...] button to specify an MI file. Default=off.
