To make a scene render faster, do any of the following:
- For Maya software, 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:
- Select
File > Optimize Scene Size >
to turn options on or off to optimize everything in the scene and to remove unused or non-valid elements. See
Optimize Scene Size Options.
- For Maya software rendering, use Block ordered texture set up. See Cache texture files using BOT (block ordered texture).
- If the scene contains objects with construction history and you no longer need it, delete it. See the Construction history for details.
- Select
File > Optimize Scene Size >
- 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, Test Resolution (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 Optimize Instances in the Render Settings: Maya Software tab to improve rendering performance.
- Turn off motion blur if you don’t need it. 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.
