I am trying to find a way to change the animation after the fact without deleting all the layers and start over. that’s is apply it to one property and not all the properties separately. I see the second expression works the same as the first when placed in the Time remapping property and does not hold the position when the layer reaches the last keyframe. the reason I tried TR is because I want to place my animation inside the precomp so I could change it once, and for it to affect in the master comp on all it’s duplicates.
thank you Dan. it works. I can now animate only once, and have the change affect all the layers. exactly like the references.
I found that precomping the animation and using time remapping for the property gives me greater flexibility in recreating the effect. I don’t have to reference different parameters because TR will contain all of them.
