emitting 3d comps in particular
Posted by Graham Smith on December 18, 2008 at 12:36 pmi would like to make some 3d objects and use them in particular
can this be done?

December 18, 2008 at 4:13 pmThere is a good tutorial on a way to use AE 3D objects in Particular here: https://www.graymachine.com/v3/07-particle-orientation-in-trapcode-particular.html
When I use 3D particles, I typically create a looping animation and use that in Particular Set the particle to loop with a random start time. Just keep your precomp size pretty small so AE doesn’t bog down.

December 18, 2008 at 4:22 pmyou can’t use actual 3d objects from maya or max, but you can fake it sometimes.
1. Make a new comp the size of your particle (ie:30×30) within your existing comp.
2. Within that comp make something 3d like two 2d layers intersecting each other, parent them to a 3d null object and rotate the null. You should now have a 3d looking object rotating
3. Go back out into your main comp, pick a custom particle in particular and select your new 30×30 comp as your particle.
You should now have a fake 3D particle emitting. you can make some cool stuff this way, but it won’t work for every project.
hope this helps.

December 18, 2008 at 5:18 pmnice thanks very useful indeed
what im thinking is making a pre comped thing like a building for instance and using the 3d precomp
as the particleas this possible anyone?

December 18, 2008 at 6:02 pmI’ve never tried it, but I would think that you probably would have to build the planes of the building in your particle comp, and then turn on Collapse Transformations so that it would be a 3D element in your main comp. Even then Particular might do something that would flatten your particle image, since it, like many things in AE, is not truly operating in a 3D space – more like 2.5D
Make sure to post the result if you work it out!
Cheers,

December 18, 2008 at 8:02 pmCreate your building in a precomp and nest it into the comp with Particular. Using Particular’s custom particle, you can select the 3Dbuilding that you created in Particular. The only tricky bit is setting the Time Sampling for Particular. Usually you will set it to Random Loop.
Random Loop will force Particular to emit particles with a random start point and when the particle reaches its inherent end-point, the particle will loop to its inherent start point and continue again in this manner until it dies off. Also keep an eye out for the size of your particles – too small and they may pixelate if they get too close to the camera and too big and they’ll bog Particular down to a crawl.
For this to work, ensure that your particle is created in such a way that it is seamlessly loopable. Also, you can use renders from 3D software as 3D particles with Particular or even Particle Playground.
