Fluid nCache > Create New Cache

If you have multiple fluid objects selected, fluid caches are created for each of the selected fluid objects or a single cache (One File per Frame, One File) is created for all the selected fluids. Fluid nCaching works similar to nCloth caching. See Create or import nCaches.

Fluid nCache > Create New Cache >

Opens the Create Fluid Cache Options window. This window lets you specify the name, type, and location-on-disk for the caches you want to create.

Cache Directory: Specifies the location on your server or local disk to which the fluid cache is saved. The folder icon () allows you to browse to a different directory than the default.

If your scene has been saved to disk, then your fluid cache files are saved to folders named after their scene files in the \maya\projects\default\data\ directory by default. If your scene has never been saved, then your fluid cache files are saved to the \maya\projects\default\data\cache directory by default.

Cache Name

Specifies the name for the fluid caches you want to create.

Use as Prefix: Sets the Cache Name as a prefix. When on, the base names of your fluid caches are the current fluid objects’ names plus the specified Cache Name as a prefix. For example, the cache file names for an fluid object named Cape with the prefix red are as follows: red_CapeFrame1, red_CapeFrame2, red_CapeFrame3 and so on. This option is only available when One File Per Frame is on.

File Distribution

Select one of the following File Distribution options.

One File Per Frame: Specifies that one fluid cache file per frame of the specified Cache Time Range is created. If multiple fluid objects are selected, one fluid cache file per frame is created for all the fluids.
One File: Specifies that one fluid cache file for the specified Cache Time Range is created. If multiple fluid objects are selected, one fluid cache file is created for all the fluid objects.

Cache Time Range

Select one of the following Cache Time Range options.

Render Settings: Specifies that your current Render Settings determine the Cache Time Range.
Time Slider: Specifies that the current playback range in your Time Slider determines the Cache Time Range.
Start/End: Specifies that the range of frames between (and including) the specified Start and End times determines the Cache Time Range.

Start/End: These fields let you specify a Start and End time for the Cache Time Range.
Evaluate every frame(s) and Save every evaluation(s): When creating a fluid cache, one sample of your fluid effect’s simulation is taken every frame and saved to your cache by default.

Evaluate every frame(s) specifies how often samples are taken during fluid cache creation. For example, a value of 2 caches the simulation of the current fluid effect at every other frame of the Cache Time Range.

Save every evaluation(s) specifies which samples are saved during fluid cache creation. For example, a value of 2 specifies that only every other sample specified by the Evaluate every frame(s) option is saved to your fluid cache.
Cache: Specifies which fluid properties are saved in the cache file.
