Re: Particle Event control by a Texture Map

Hi Guillaume,

Make a clone of your shape, apply a push op, cage deform (or maybe gator) your particles onto it.

Animate your push op to get them coming off - then maybe look at overlaying some forces on top of the particles.

Cheers,

Alan.

Hi,

 

I need a particle effect like this :

 

Frame 1 : a particle cloud is shrink wrapped around a shape. The cloud doesn't move on first frames.

Frame 20 : there is a particles emission. No new particles created, only the existing one "emit" from the shape. It is not an emission in xsi particle sense, they just go away from the shape, floating and falling.

 

So I create  a cloud with a given number of particles ( same number as points on the "shape object" ), stick all the particles on each points of the "shape object" by script and set an initial state.

 

Here is my problem :

To animate the particles I imagine two solutions. First one using forces. It doesn't look as the good one because forces affect all particles and some particles need to stay on the shape for a moment... The way to go is maybe with a particle event. I wrote a particle event to simulate a gravity force. It works fine but is it possible to connect a particle event to a map ? 

 

Maybe I miss something simple. Any idea is welcome.

 

Cheers
