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 "" end registry where 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. Geometry Caching group Geometry caching lets you save the translated scene contents to a temporary file for reuse in subsequent renders. This can save time by omitting the translation step, especially with geometry-heavy scenes. Two levels of caching are available: standard and locked. Enable When on, rendering uses geometry caching. During the first render, the translated geometry is saved to the cache file. Then, in subsequent renderings of the same scene, the renderer uses the cached geometry for any unchanged objects instead of retranslating it. Any changed geometry is retranslated. Default=off. This control is available on the Rendered Frame Window lower panel as Reuse > Geometry on page 6082. Lock Geometry Translation When on, sub-object-level changes such as vertex editing or adjusting a modifier such as Bend are ignored and don't cause retranslation. However, object-level changes such as moving or rotating an object are retranslated. This control is available on the Rendered Frame Window lower panel as Reuse > Lock Geometry Translation on page 6082 ( button). Clear Geometry Cache Deletes the cached geometry. This control is available on the Rendered Frame Window lower panel as Reuse > Clear Geometry Cache on page 6083. mental ray Renderer | 6321
