> And as a micro follow-up, is there a way to wiggle just one dimension, without separating dimensions?
There are
examples for doing this in After Effects Help, including this example in
the section on the wiggle method:
This example, on a two-dimensional property, wiggles only along the y axis:
freq = 3;
amp = 50;
w = wiggle(freq,amp);
[value[0],w[1]];
