Layers skew when rotating

[Steve Roberts]

It sounds like you’re viewing a non-square pixel comp without pixel aspect ratio (PAR) compensation on. It’s one of the little buttons below the comp window. Check the help for “pixel aspect ratio”.

Let us know if that’s not it.

One way that can happen is if your rotating layer is a child layer and the parent is non-uniformly scaled (x scale and y scale are not the same).

Thanks Dan for your input, but ultimately it was the problem that Steven described. It’s now been resolved. Thank you both for your help.

Hi Ryan,
I’ve got a similar problem..Can you tell me how to resolve it?

Thanks,
Ajay

Hi Ajay,
Did you try out the suggestions from Steve & Dan who replied to my original thread? Personally, my problem was solved by Steve’s suggestion – I clicked on composition settings, and my pixel aspect ration was on widescreen rather than square pixels. Selecting square pixels sorted out my issue instantly.

Hope that helps,

Ryan

I’m having this problem and toggle-ing the PAR switch did not do it.

In this case I think the problem caused because I am rotating a a non-uniform scaled object with a uniform child. What would be a work around for that?

Hi

I am encountering the same problem, no pixel-aspect irregularities.
I have done this many times before without this happening, could this be a bug with the new version (CC2014)?
What i had to do to work around this was to first parent my layers in the parenting stack to null objects, then parenting the null objects to each other.

Is one of your parents scaled non-uniformly?
I haven’t heard of any bugs to do with scaling/skewing issues in the new version.

Yes, i guesss that is what is causing the problem, i had a stack of solids that were non uniformly scaled to begin with.

Dan,

first of all THANK YOU for you excellent work on expressions and you generosity on sharing this with us.

I’ve had this non-uniform scale issue many times, is there a workaround if someone MUST use non-uniform scale?

I’ve found an old post from you recommending this expression

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

but it did not work for me, maybe because I’m working with 3d layers.

What if those layers are a 3d collapsed precomp?

best regards

Flávio
