NAKD BOXES…Particles from object that do no collide HOW?
Okay so here is the effect i wish to do.
https://www.ventilate.ca/news_updates/2006/feb_07/movies/nakd.movI get that it has to be done in some way shape or form with particles generated from an object or objects. I also get that these particles are most likely produced from a texture (or using matterwaves in cinema) What I don’t get is how to prevent particles that are generated from being generated one on top of another. how to keep them from colliding or I should say how to emmitone from each face of the polygon no more no less? The new Mac commercial (with the album art0 that Logan just put out does the same kind of thing.
I am thinking I might begin a little learning tutorial and continue this on. Step by step with where I get hung up.
Any help is appreciated. Thanks.

Trying to prevent existing particles from intersecting, especialy when they are as close to another as in that animation, is hopeless. You have to emitt them in a way that they are not intersecting in the first place. I would creat simple proxy objects where all polygons have the same square size and then emitta particle for each single polygon. The points will give you position and alignment. After emission maybe adjust a weight map accordingly so you know from which points you already emitted particles. Triggering the emission can maybe done using a Null or another object and move it along the proxy. Measure the distance between points and the object and if it is below a threshold and the weightmap sys there was no prior emission trigger emission.

This is alot of great information. I will look into all of this as soon as I get home. I was wondering if you could expand on a couple things foe me real quick though.
“… and then emitta particle for each single polygon. The points will give you position and alignment.”
Is this a setting? I couldn’t find out specifically how to do this. Do I need an expression?“…adjust a weight map accordingly so you know from which points you already emitted particles.”
I am not familiar with what weight mapping does exactly. Is there a one sentence description that you could throw my way.Thanks again, sounds like you know what your talking about that’s for sure.

Seems the cow forum ate my reply from yesterday :/
Ok, instead of typing it all again you can find an example here

It’s a bit quick and dirty but it does the job.
