Specifies the simulation data that will be saved to a server or local hard drive when the current nParticle object is nCached.
Caches Particle ID, Age, position, and rotationPP.
Caches Particle ID, Age, position, rotationPP, velocity, angularVelocityPP, and LifespanPP.
Caches the following nParticle attribute data: Mass, radiusPP, opacityPP, rgbPP, incandescencePP, spriteNumPP, spriteScaleXPP, and spriteScaleYPP.
Caches the following nParticle attribute data: Particle ID, Age, position, rotationPP, velocity, angularVelocityPP, LifespanPP, Mass, radiusPP, opacityPP, rgbPP, incandescencePP, spriteNumPP, spriteScaleXPP, and spriteScaleYPP.
Specifies how ramp attribute data is evaluated. When on, the ramp output is re-evaluated using the cached input attribute rather than the cached data. This attribute is off by default.
If you turn off Post Cache Ramp Evaluation, you need to scrub your simulation before ramp attribute data is read from the cache again.
When turned on, the motion your nParticle object is saved to memory (not to disk). If you cache data in memory for emitted nParticles, and then later change the rate or another attribute of the emitter or emitted nParticles, you must disable the cache to see the effect of the attribute change.
