Solvers > Create Particle Disk Cache >
These are descriptions of the options in the Particle
Render Cache Options window.
- Cache Directory
-
- If
you don’t specify a name, Maya uses a directory that matches your
current scene name. If that directory doesn’t exist, Maya creates
it.
- If
you specify a name that is different from the current scene name,
Maya prompts you to be sure you want to use it. It is generally
preferable to use the name of the scene because if two scenes are
cached in the same directory, a new caching operation overwrites
the old cache.
This same prompt appears if you cache a scene,
save the scene under a different name, and re-cache the scene. When
you try to re-cache, Maya detects that the cache name now differs
from the scene name and asks you to confirm.
- Don’t
specify an absolute directory name. Maya considers the cache directory
always to be relative to the Particles directory of your workspace. However,
you can set the Particles directory of your workspace to an absolute
directory name using
File > Project > Edit Current.
- The
name of the directory used is stored with your scene, so if you
change the name of the scene, Maya is still able to find your disk
cache. The name is stored in the dynGlobals node (see
Editing particle disk cache settings).
- Use Render Settings Range
-
If you turn on this option, Maya caches particles for
the frame range specified in the defaultRenderSettings instead of
for the current playback range. Turn on this option if you plan to
use the render settings range in your render.
- Only Update particles
-
If Only Update particles is
off (default), the particles will be evaluated by normal DG evaluation,
and the cache is guaranteed to have the same result as in interactive
playback. If Only Update particles is on,
Maya optimizes the evaluation by triggering the evaluation only
on particles. This optimization can create a discrepancy if one
particle system is dependent on another particle system.
- Particle systems to cache
-
Specify to cache either Selected or All particle systems.
If Selected is specified, then
only visible (non-intermediate) particle systems are cached.
