Is anyone aware of an active Trapcode forum? I'm trying to find out how to control the flow rate of the Particular emitter but having no luck. I'd like to simulate heart rythm in blood flow but I can't figure out how to slow down and speed up the Particular emitter flow rate.
You don't - that is unless you care to have a ton of pre-run time and animate the pulsating emitter, because all evaluation is based on the poarticle emission. It's the wrong approach, anyway. The volume of blood is constant, only its speed changes. And that kind of is the answer - you animate the strength of the forces like the wind to accelerate and decelerate the flow.
