Hi guys,

I have a line when I make a mask + duplicate with mask inverted.

The line goes away agains a transparent background when i add “Alpha Add” but as soon as I put a color behind it: EDGE!

Any ideas how the Alpha Add might also work with a Background?

with bg and alpha add
without bg and alpha add

Thanks Oleg! ☺

Good to know that option number 1 is to much of a hassle

Just stumbled into the same issue.

Changing the render order is no option I presume? I tried scaling a precomp with Set_Mattes in it, but it broke up the scene.

I tried scaling with the “Transform” effect, but then the resolution goes down. The only option I saw is scaling up the whole PreComp. Is this the best way to to it? Greatly enough it doesn’t break when I scale inside of the Precomp where the Set Mattes are.

I hope there is a better way, because scaling my PreComp is heavy stuff for my computer 😉

???? I should have known. Thanks for clearing it up –> It works now.

I might have cheered too soon.

It gives me an error:

expression result must be of dimension 2, not 1

Is this an easy fix?

Hi Oleg,
Thanks for helping out.

I made option 1 and 2 (where I used Point Control) for option 1.

Option 2 seems to work, but when I scale up or down COMPX it gives me trouble.
Thanks for having a look at it. It kills me and I have the impression I don’t understand the working of expression tools like “PointControl”.

Thanks for the help ☺

Hi Oleg,

For some reason it doesn’t work the expression you gave me. You apply it to the “Scale” Property and Child layer?

This eventually turned out quite nicely. I don’t understand the code, but it works:

s = scale[0];
L = thisLayer;
while (L.hasParent){
s = s*L.parent.scale[0]/100;
L = L.parent;
}
s

I’m having the same sort of issue. I have a PreComp that is 2160×3680 and I put this in a smaller comp. Now parented this Precomp to a null, but now I’m not able to see how far I scale my PreComp. Since I don’t want to go beyond the maximum resolution (scale > 100) I would like to have some kind of controller that will tell me when I reach 100.

Of course I could check this by unparenting my PreComp from the null, but is there a way where I can check the absolute/global scale value at all times even when it is parented to another layer and therefore relative data?

[Wouter Dijkstra]

As it seems for now whenever I try one of the above mentioned options, the Null will always move to fast.

So it’s like this:

COMPX:

Null is repositioned to the lower-end of the Foot and moves perfectly with the Foot.

COMPY:

Null is parented to the Null in COMPX and I have to find it somewhere far outside of the comp + It doesn’t stay on the Foot in COMPY

I’m stuck :p

[Wouter Dijkstra]

I am not sure if it is important to mention, but the Nulls in CompX are also parented in this manner:

Null1 parented to L_Foot
Null2 parented to R_Foot

I appreciate all help and knowledge 😀
