Cache Time Range

Specifies which frames are cached. It is easiest to cache the entire frame range of the Time Line. However, you can create smaller cache files to conserve disk space by caching only the frames where objects jiggle.

Time Slider

Caches all frames of the Playback Start/End range.

Render Settings

Caches the frame range specified in the Image File Output section of the Render Settings window.

For more information, see Render Settings window in the Rendering guide.

Start/End

Caches the frame range specified in the Start/End Time boxes.

Start Time End Time

Sets the cached frame range. Available only if you select Custom for the Cache Frame Range.

Sampling

Oversampling and undersampling specify how often Maya calculates jitter per frame.

Over

A Rate value of 2 or larger might increase the precision of the cached jiggle in scenes where a jiggling object collides with a rigid body quickly and repeatedly.

Under

A Rate value of 2 or larger decreases the precision of the cached jiggle, but quickens the caching operation. An Under Sample Rate of 2, for instance, means Maya calculates jitter once every two frames.

If a jiggling object collides unrealistically with a rigid body, select Over Sample and set a Rate that matches the Over Samples setting available in Solvers > Edit Oversampling or Cache Settings.
