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.
If
the scene contains objects with construction history and you no
longer need it, delete it. See the
Construction history in
the Basics guide for details.
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, 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 (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.
