Adjust scene anti-aliasing parameters (Maya software)
 
 
 

Maya separates edge aliasing parameters from shading aliasing parameters to give you more control over image quality and performance.

You can adjust anti-aliasing settings for edges, shading, multipixel filtering, and motion blur in the Anti-Aliasing Quality section in the Quality tab of the Render Settings: mental ray tabs.

For details on the settings, see Adjust anti-aliasing.
