To make a scene render faster, do any of the following:
- Diagnose the scene to find ways to render the scene faster using Render > Run Render Diagnostics. You can use this tool to monitor how well you optimize the scene and to search for limitations and potential problems that
may occur. For more information on render diagnostics, see Run diagnostics.
- Perform scene optimizations:
- Avoid memory swapping by:
- Closing all applications before rendering to maximize the amount of memory available for rendering (including Maya if rendering from a shell or command line).
- Setting the TEMP or TMPDIR variable as the location for temporary render cache files: -TMPDIR (Linux) or - TEMP (Windows and
Mac OS X) to make plenty of room for temporary rendered files. Make sure that the value of those variables points to a local,
fast hard drive, not a network drive.
- For Maya software and mental ray for Maya, (Render > Test Resolution) lets you select a reduced resolution to test render the scene. For more information on test rendering strategies, see Visualize interactively with IPR.
- For Maya software, if the scene contains several identical surfaces (for example, multiple spheres), use in the Render Settings: Maya Software tab to improve rendering performance.
- Turn off motion blur if you don’t need it (the Vector renderer has no motion blur). For the Maya software renderer, use 2D
motion blur instead of 3D motion blur when possible. See 2D Motion Blur global attributes and 3D Motion Blur in the Render Settings window for details.
