  Adding random spikes to wiggle…

  Posted by Pierpaolo Ferlaino on June 24, 2014 at 7:56 pm

  Hi.
  I’m trying to emulate the Misfire GateWeave plugin (it does not retain my layer’s transparency).
  I used a wiggle expression in the layer’s position and it works quite well but Misfire GateWeave randomly add some spikes (they call it noise frequency) to the wiggling movement making the layer x position suddenly shift and come back in place.
  How can I achieve this?

  Thanks

  Maybe you can tweak this to get something that works:

  amp = 25;
  freq = 2;
  w = wiggle(freq,amp)-value ;
  value + w* (length(w) > .9*amp ? 5 :1)

  Thanks Dan.
  Tweaking your expression did it.
