Apparently, Wiggle Stroke (Cycore Effects - Plug-ins - After Effects) is meant to be included. But if it's been renamed, it's now something so obscure I can't find it :/
I'm on CC 2014 and have all the CC [...] effects. I'm just trying to wiggle a path without using the rather buggy inbuilt "wiggle path" option.
Why do you think that Wiggle Stroke is meant to be included with After Effects? It is not. The page that you link to is for Path Tools, a Cycore product that is separate from the Cycore HD effects that are included with After Effects.
Oh. Well, if it isn't, it isn't - but the only reason I asked was that I tried to buy the Path Tools effect and there's a note on the Cycore site that says "CycoreFX HD included in After Effects CS6. Sales stop May 21st, 2012."
Probably confusion on my part!
