  precomps, expressions, and World space

  Hi all,

  This forum is a fantastic resource. I use it heavily, and am very grateful!

  Comp Structure:

  comp "A"
- Null "C"
- Null "D"
- precomp "B"
- Null "E"

  Assume that all items have been moved, rotated, and/or scaled in their respective contexts.

  I need to dynamic parent Null ‘E’ to Null ‘D’. Put differently, if I translate Null ‘D’ within comp ‘A’, Null ‘E’ will move along with it.

  In my limited knowledge of AE, I think I need to

  1) get the ‘toComp’ position of Null ‘D’ within Comp A
  2) pipe that value into precomp ‘B’
  3) get a ‘fromComp’ value to pipe into Null ‘E’

  If I’ve done it properly, Null E should track exactly with Null D in Comp A space.

  Make sense?
