Floating with Shadow
Hi There,
So I have a picture of a girl in a box, with a shadow under it. I have a pretty good float going on with the picture using wiggle(.5,5) and I can apply this same expression to the shadow but I would like the shadow to scale smaller when the box goes up and bigger when it comes lower. Is there a way to do this?I am not great at expression at all so if I question to your responses it is to learn not to doubt.

It’s difficult to say without knowing exactly what you’re working with, but in general, I think I’d use a Position expression like this to tie the shadow’s x position to the box’s x position:
[thisComp.layer(“box”).transform.position[0],value[1]]
and a Scale expression like this to tie the shadow’s scale to the box’s y position:
yMin = 285;
yMax = 315;
sMin = 95;
sMax = 115;
y = thisComp.layer(“box”).transform.position[1];
s = linear(y,yMin,yMax,sMax,sMin);
[s,s]The first for parameters in the second expression are very dependent on the particulars of your comp.

Thanks I will play around with it a little.
