PFlow – Assigning Controllers to Parameters
Just a super quick tutorial on how to assign a Waveform (or any controller for that matter) to the Emission Rate of a PFlow Birth Operator.
Waveform2EmissionRate AVI 6mb – Techsmith Codec TSCC (Here)
For some reason the quicktime has some crappy artifacting and it is twice the size. If anyone is interested: Waveform2EmissionRate QT 13mb
You can stack multiple Waveforms in the same controller to achieve varied rates of birth, for example a large burst of particles the tapers down in steps.
Of course you can keyframe all this by hand with a bezier float controller too if you want 
Thank for the tutorial.İt’s realy good tutorial…
