Alright, I have tried to find an answer to this a few times over the past couple days with no avail. I have checked many forums, and dug through adobe's expression language page, and haven't found an answer.
Im trying to find a simple solution for maintaining a world scale to an object. I have a complicated rig built... with 40 shape layers parented to individual nulls. Those individual nulls daisy chained parented, all the way up to a master control. That master control null needs to control the scale and rotation of the entire rig, and the individual nulls are intended to control the position of the shape layers via the null's scale and rotation.
Is there a simple expression that I can put on the scale property that would maintain its scale when I animate the parent nulls?
