Solvers > Create Particle Disk Cache
Creates a particle disk cache. For details on how to use create this, see Particle disk caching.

These are descriptions of the options in the window.

- 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).

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.

If 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 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.

Specify to cache either or particle systems. If is specified, then only visible (non-intermediate) particle systems are cached.
