I need to animate a particle flow to simulate a “Brownian Motion” It is describe as “Random irregular motion of suspended particles”.  Anyone have any tips.  I’ve used particle system before to animate particles flowing thru a filter and getting trapped, but the “random irregular motion” has got me worried.

What 3rd party plug-ins are out there that are more advanced than MAX’s Particle Flow?

Thanks,
Kenn

If you’re looking for something like this video on youtube, then it’s pretty simple with pflow. In this scene I use a noise controller on a helper and wired that to control the speed amount in pflow. For some reason putting a noise controller on the speed operator directly won’t work. Then it’s just a matter of creating a loop with age tests to make it look random.

I don’t think you’ll need them for this, but here are some other particle plugins:
