View Full Version : moving particles around a torus, how?

03 March 2008, 12:26 PM
Hi Guys after being in After Effects for years have taken the 3d plunge and spent the last 6 months trying to get to grips with Max version 8 and become obsessed with the particle systems and Afterburn.

Anyway, have been trying to get a nuclear blast type mushroom cloud for ages for a project and kind of getting there now but it still needs work, at the moment am birthing particles at frame 0 on a noise modified hemisphere then having them wind blown upwards via spacewarp here is my current version minus all the bells and whistle glows and lens flares....

What i want to do, to get a more complex rolling motion in the head, is to have a keyframed torus rising up and have particles that have been spawned on it to rotate around in an upward motion carrying on inside it to appear again at the bottom and so on.

As in this hastily made image, like a torus, particle conveyer belt kind of thing. (

Is this movement possible with pflow am using Version 8 of the MAX.

Am not too bad with pflow but still have a long way to go.

Thanks for looking.

it is possible with position object. "Lock on Emitter" should be checked then.

i set up a maxfile for you that deals with allignment too. the operators are inactive(grayed out) atm tho. unfortunately its max 9!

with kind,

WOOOW just looking at your motion blurred thumbnail illustrated exactly the motion I want, just ran the file and thats IT!

Thanks a million, now will spend the time working out the method and application of it, once again cheers, you nailed it.

This illustrates the perils of jumping in at the deep end without learning the basics first can't beleive it was just the Torus properties ROTATION being animated, Arrrrrrrrgggghhhh. (Pulls even more hair out.)

Thanks again.
