One layer scales up while the other scales down
Hi folks-
What would be the simplest way to make several layers (such a 6 layers making up a cube) “explode” outwords. In other words, make them all move away from the center.
I think that this might work:
– placing a null in the center
– making the null a parent to the layer
– scaling up the null
– Creating some sort of expression to reverse scale the layers as they are pushed outwards – making it appear as if they are staying the same size. (This is where I need help)Does that make sense? Is there a simpler way?
I may want the layers to rotate/spin as well as change their opacity (go from 100% to 0%, which should be simple using the linear function connected to the scale)
Thanks.

That should work. This sould do it:
s = 100*transform.scale[0]/parent.transform.scale[0];

Awesome – thank you so much. That worked.
But, I;m getting some odd results when I try and do the rotation…
The null scales up from 100% to 2000%, and I’m trying to use the linear function to take the nulls scale and translate that so that the pieces go from 0 degrees of rotation to 720 ( full rotations). But after 360, they stop rotating.
Any idea why?
The code I;m using is:
X = thisComp.layer(“Null 4”).transform.scale[0];
linear(X, 100, 2000, 0, 720)Thanks.

Hard to say. It works for me.
