parent/child linking without scale.

[Dan Ebberts]

Try this Scale expression for the child:

s = [];
ps = parent.transform.scale.value;
for (i = 0; i < ps.length; i++){ s[i] = value[i]*100/ps[i]; } s Dan

Hi Dan, thanks for the help.

No luck this end I’m afraid, the layer still scales smaller and larger, I wonder if it might have something to do with how many children are stacked above it, I don’t know. .

I found an expression of yours for the same thing only excludes rotation, but I couldn’t adapt it to work for scale.

value – parent.transform.rotation

maybe this will offer a clue?

Yup – that solution will definitely not work if the parent has a parent. Try this one:

L = thisLayer;
s = transform.scale.value;
while (L.hasParent){
L = L.parent;
for (i = 0; i < s.length; i++) s[i] *= 100/L.transform.scale.value[i] } s Dan

Success!!!

Thank you Dan, I should be able to keep this shot within the comp bounds now whilst it’s deforming, it’s a lot of juggling around with some of the layers being delayed to scale at different times, but I think it’s going to look insane, I also got past my 3D warps problem so in addition to the collapsing of the layers, they can also be warped in to additional 3d shapes, crazy 🙂

Thanks Dan, I envy your talents 😉

Hi Victor,

4 years later in case you still figuring it out.

I believe you were getting that error as you were trying to parent a 3D layer to a 2D layer.
That’s why you were getting the error.

Hope it still helps.
Cheers
