TP and Dynamics- Possible to turn off dynamics for individual particles?

[Darby Edelen]

Is there a specific reason you only want to use one particle group?

Well, if I used two particle groups- I’m guessing one would be set as ‘sticky’ particles and the other as more ‘rigid body’ particles. I’ve attached a .mov file illustrating why I think one particle group is needed- so that the rig can travel across a room and interact with various objects, without having different particle groups being switched on and off depending on where the emitter is traveling.

I actually found a solution- video below.

I used a single emitter with a rigid body tag along with an attractor for the sphere. Much simpler than what I was thinking, and it works pretty well. I suppose you could use 2 emitters, depending on the look you’re going for, but I didn’t really want too many sprinkles falling off once they stuck (the particles falling on top of other dynamic particles)

Let me know if you have any other ideas/ thanks

Your dynamics solution is better because you can keep the sprinkles from penetrating each other but for what it’s worth if you were using TP only you would change the group as it hits the sphere (then freeze the new group).
It’s hard to do anything TP group related when you have used Dynamics on the particles, once the TP emitter gives the particles their placement and initial speed etc the Dynamics moves the objects away from where the TP particles are (which is where TP actions like PDeflector happen) so the timing is wrong

Thanks for the input, it’s always nice to have multiple ways to solve a problem.
