I have multiple shape layers, and I want to add Wiggle Paths to all of them.
One way of course is to manually add to each of them.
Is there a way to add it to all of them at once? Specially is there a way to control them all in one place? so if I wanted to change the Wiggle parameters (like size, speed, correlation ...) I can change them all at once?

  • Thanks @poor . I didn't know you can add "path operations" to Null layers. let me try it. – Ali Apr 4 '15 at 16:07
  • Ah, I was also thinking I may find an effect to do the same thing – Ali Apr 4 '15 at 16:10
  • The only way is to drive your values by Slider Control's created on a Null, but this could take ca. 20min to setup. – p2or Apr 4 '15 at 16:13
  • I like the idea of a "slider control" why don't you put it as an answer so that I can accept it? – Ali Apr 4 '15 at 16:18

Use Expression Slider Controls to drive multiple Shape Layer Wiggle Path Values.

Here is an example of driving Size and Detail values of the Wiggle Path Property on 6 Shape Layers with 2 created Slider Controls on a seperate Null Layer:

Note: To save time, it's a good idea to create one shape layer first, set it up as described below and duplicate it afterwards to maintain the expression links.

  1. Create a Shape Layer and a Null Object
  2. Add Wiggle Path Property to the Shape Layer
  3. Add a Slider Control to the Null for every value you need for animation (size, speed, correlation ...) and name it like these for a better organization
  4. Select the Null and go to Effect > Expression Control > Slider Control
  5. Open up the properties of the both layers by clicking on the small arrow > right beside the layer's name to see the values of the Wiggle Path and the newly created slider control at the same time
  6. Holding down Alt while clicking on the stop watch of a Wiggle Path Value like the Size or Detail, this automatically will insert an expression
  7. Use the expression pick whip and drag it onto the predefined Slider Control of the Null before to link/parent it, for e.g. the Size of Wiggle Paths, this should create something like: thisComp.layer("Name of the Null").effect("Size")("Name of Slider Control")
  8. Repeat the process of parenting the Wiggle Path Values to the Sliders as long as all needed values are parented to slider controls correctly
  9. If you duplicate the Shape Layer with CTRL+D now, all expressions will retained for the duplicated layers

    @Ali Cleaned up the answer, added a screenshot and a gif for better understanding. – p2or Apr 4 '15 at 18:07
