particles form an object
Hi,
I would like to use particles to form an object or a text. The particles should be emmited from one point and then the particles are all fitting in an object or a text. I don’t want the particle just to reveal (as a wipe) but really that each particle become a part of this object or text.

Bud,
I’ve done something similar – particles form a logo and then get blown away like sand – using the Shatter effect with a picture of TV noise as a shatter map, and a 4 way gradient map to control which areas are formed (or blown away) first.
To get the particles to form instead of blowing away, I just reversed the footage and played around with the gravity setting so the particles would be coming from the right area.

CC Snow has an alpha build-up feature. It won’t do what you want but it’s a good place to practice since you’ve already got it on your AE ssytem.

This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

I’d use the layer as an emitter (if it’s masked, pre-compose it) and use block dissolve or similar to dissolve away the layer.
Match the block size to the particle size visually.
Animate the number of particles emitted from maybe 2000 down to zero.
Tweak until it looks like a good explosion/dissolve.Then reverse the whole thing, nested in another comp.
Or use shatter. 🙂

I’ve done something similar with a picture i wanted it to fly in and fill in the picture from left to right. ayatoweb.com has a very nice walk through kinda guide how to do it. not a full tutorial but its easy to pull off. basically it using the shatter effect but reversing it so that it fills in you can pretty much get the shap of your “particles” to be anything you want. look into it it might do the job your looking for to simulate particles filling in an object or logo.

Thanks to all of you.
The differents ways seems interesting, reversing the animation seems a good way. I’ll try, and see the best for what I want.
My main problem is to join this one point to the object. So I think I will divide it in two part : emmit from one point and reverse the animation emmit from the object layer. The particles should joint in the middle.
But it’s kind of hard to manage particles in 3d space. Do you have an tips about that ?
I don’t think there’s a way to give them a 3d-path in After fx ?Thanks again

If you check the Trapcode website, there should be tips on giving Particular particles a path.
