Caching can play a key role in simulation. A cache file stores all position, velocity, dynamic, and render data for your nParticle simulation. Having a cache reduces the number of calculations Maya performs when playing back or rendering scenes because the cached simulation data can be read from disk, instead of being dynamically computed. Rendering from an nCache is system independent, meaning that you can render an nCache that was created on a different system platform and achieve the correct simulation results.
