Particle Playground in 3D? quick question.
on Jul 7, 2012 at 4:04:26 pm

Yes, I know Element is coming out. But I can make PP do a lot of things I want it to. I can get it to rotate, add custom images, etc. The problem is, if I try to link it to a 3D null, I get an error.

This is presumably because there are only 2 directions in PP (x, y). I did not include the error, because I think is pretty straight foward. Is there no way to link the emitter to a 3D object?

I still think that Particle Playground is a great particle system, once you understand how to navigate around it. But I am kinda bummed about the lack of 3D capability. No way around it, its a 2D preset...eh?

[Dave Andrade] "Yes, I know Element is coming out. But I can make PP do a lot of things I want it to."

Element is a particle array; Particle Playground is a particle generator. They are both kinds of particle systems, but they don't do the same thing. Element is more similar to Trapcode Form than it is to Trapcode Particular, just with a heavy dose of righteous 3D.


[Dave Andrade] "This is presumably because there are only 2 directions in PP (x, y). I did not include the error, because I think is pretty straight foward. Is there no way to link the emitter to a 3D object? "

You have to transform the 3D point's position to the corresponding 2D position. Alt-click the Particle Playground > Cannon > Position stopwatch, and enter the following expression:

thisComp.layer("Null 1").toComp([0,0])

Please note that while this will track the apparent position, Particle Playground doesn't understand depth, so the particles will not appear to get smaller or larger, even though they will stick to the object, as it recedes or advances in Z-space.

Perfect Walter, thanks. I guess if I want to make the appearance of depth I will have to create a layer map and adjust the scale accordingly.

Despite my attempts to avoid it...and even with CC Particle World, it appears as if Trapcode's Particular really is the best way to generate custom particle (meaning "user created" particles) in 3D space within After Effects.

The price is a little out of my reach right now, but it appears to be worth the investment. Again, I appreciate the info!!

Yes -- I do think Particular is a must-have. Things like this are either very hard to do or maybe even outright impossible with other particle systems, but very straightforward in Particular.

Good luck with your project!
