What is nCaching?
 
 
 

You can save your simulation data to a server or local hard drive by caching your Nucleus objects or fluid effects. nCaches are special Maya files that store the simulated point data of your simulations. nCaches also connect to the nucleus nodes in your Nucleus systems, which allows both cached and uncached Nucleus objects to interact.

nCaches are useful when you want to reduce the number of calculations Maya performs when playing back or rendering scenes that contain simulated Nucleus objects or fluid effects, and they allow you to easily direct, mix, and edit your simulations in an intuitive, nonlinear manner.

NotenCloth caches only store information about the XYZ positions of an nCloth object’s vertices, not the translation, rotation, or scale of the nCloth’s Transform node.

You can use nCaches to do the following:

You can create nCaches for your Nucleus objects from the nCache menu, and for your fluid effects from the Fluid nCache menu. nCaches can be edited from the Attribute Editor or the Trax Editor.

NoteThe nCache file format is an open format that can be read with standalone applications. For more information, see the example Python script cacheFileExample.py located in the devkit\pythonScripts folder of the Maya 2009 install directory. This example script demonstrates how to parse the cache description file and its associated data. See also geometryCacheConverter in the API guide.
