Position Percentage
Hello,
I having a null (Null 1) to control the position of a bunch of layers with a different multiplier to make it have some faked parallax.
But I’m wondering if there’s an expression to use so when I put it on the positon properties of a layer, the object remains in it’s original position.
When I apply the below expression on the position it changes the original location. (Which I totally understand why, I just don’t know how to fix it.) Also if I were to change the multiplier it be nice to have is stay in the original position as well.
thisComp.layer("Null 1").position*.5 + value -

You need to provide a reference position for the null. One way to do it is to just define it in the expression. This example assumes that the null starts at the center of the comp:
ref = [thisComp.width/2,thisComp.height/2];
(thisComp.layer(“Null 1”).position-ref)*.5 + valueDan
