Would it be possible to be able to assign wiggle to a specific layer?
I was just thinking about a character doing arm flails like in older cartoons. I couldn't find a proper example but something like Olive Oyl's arm flails in Popeye, does that make sense?
I'm not able to confirm right now, but if you place the layer into its own subpuppet (e.g., group the path in AI, place into a folder/group in PS), then apply Wiggler to that subpuppet, maybe that's a workaround for now?
OK, I was able to confirm... Wiggler on a subpuppet that isolates the layer(s) you want to wiggle, should do what you want.
