You can set the following preferences in the XGen category of the Preferences window.
To return to the default factory settings, choose 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.
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.
