Spectator effect for the background
on Jul 10, 2018 at 3:09:23 pm

I am trying to get a simple background that gives the impression of spectators in the background of a football scene. I basically need circles to idealy jump up and down as if they are cheering. The simplest but longest solution might be to animate them individually but when ever I do that the position goes all wrong.

I thought would try using an expression but isn't quite what I am after. Would anyone recommend a technique.

Here is my attempt



And I am after something more like this:

I would create a set of maybe 3-6 small, looping comps that feature one individual circle doing its own cheer, all with exactly the same duration.

Then, I'd either use expressions or a script to position them, looping them and randomizing their start times, or I'd use a particle system like Form to distribute them.

To use Form, you'd have to sequence your individual comps into one precomp that contains all of them, again, with exactly the same duration for each. Then set Particle > Particle Type to Textured Polygon, Texture > Layer to your all-animations precomp, Texture > Time Sampling to "Split Clip - Loop," and Number of Clips to match the number of comps in your all-animations precomp.

Walter, thanks, I am strugging to follow your settings but I think I am missing something

I don't seem to have the time sampling option to split clip - loop, unless I am applying CC Particle World to the wrong layer?

Walter is talking about a setting in Trapcode's Form plugin. I'm almost certain you can't do that with CC particle World.

What about just duplicating your "head" layer but first put a small wiggle expression on it. The layer number of each duplicate will change the random seed of the wiggle so each is slightly different.

This would work but I would need to duplicate the layer 100's of times, if I am understanding right.
