Joe’s advice is correct except for if you’re using the latest version of Particular. In the latest version, the particle type you should choose is Sprite. Then, under Sprite Controls, choose whether they should always face the camera or not.

You might need to scale your scene down. Parent all of your 3d elements (including the camera) to a 3d null object and scale it down a lot. See if that helps.

Since the background is going to be right up against the objects in the back, you should be able to just use Mocha to track it into the shot based on one of the items in the very back of the shot. Or, heck, the wall itself. Mocha should be able to grab onto that just fine.

Depending on what kind of camera move you have, I would have expected the Camera Tracker to work though. Is the camera moving around a lot or is it pretty stationary and just kinda handheld wobbling?

Sometimes, if your footage is MP4 (or some other variant of H.264 or H.265 compression), AE’s camera tracker has issues with it. If I have problems, I usually transcode it to ProRes before I try much else.

If that doesn’t do it, you could also crunch the colors a bit to bring out more contrast in the tracking markers and try tracking that, but, again, I think you could just do Mocha and be done with it.

The issue is likely to be the viewing settings in Particular. The “world” is probably too large. Change the values for far-off visibility.

My bad. I should have used a different function.

AE has a Copy With Property Links and a Copy With Relative Property Links – I should have chosen the latter. All you have to do is highlight the colored circles, pick one of those options, then paste it and make sure they’re above the colored ones in the timeline, then select the copies, and (in the toolbar) turn off the fill and turn on the stroke. If you want to modify the width or color of the stroke, you have to do it on the original circles.

You would have Pastiche control position and scale (and maybe rotation – try it and see).

To make it come in from all directions, use Pastiche to animate the layers coming in from a really large circle that’s outside the comp space.

Couldn’t you use it to make that image? Just have the shapes transition from one big number to a really tiny small number (to make them swoosh away).

This would be much better if Colorama gave you more precise control…

But, yes, you can. Make each circle’s fill a different opacity and then use Colorama to color each section since the color will be unique.

Also, making the object editable is more destructive. Current State to Object makes a copy of your thing as a polygonal object. This is preferred, so you can go back to whatever rig it is you’re making if you need to change something instead of losing it entirely.

That is, you can Current State to Object a crazy hierarchy of deformers, etc.
