XGen Preferences

You can set the following preferences in the XGen category of the Preferences window.

To return to the default factory settings, choose Edit > Restore Default Settings in this window. Note that this resets the preferences in every category in the Preferences window.

Cache Options

Memory Cache Size
Specifies the maximum amount of system memory used when XPD caches and Ptex files are written to disk.

See Manage XGen files and directories.

Viewport 2.0

Draw method
Sets which renderer to use when drawing primitives. When set to Hardware Instance, Maya uses the Viewport 2.0 render. When set to Legacy, Maya uses the XGen software renderer. Use Legacy to improve performance when instancing large numbers of high-resolution archive objects.

Threading

Multithreading
Turn on threading to improve the performance of primitive generation, modifier processing and patch evaluation.
