Mask with child mc problem

Hi

I’m trying to build a simple mask with 2 children mcs. The masking is almost working, but the two children only mask where they don’t overlap.

I’ve tried using a mask layer and using code, and it’s the same effect either way.

below is the code:

import caurina.transitions.*

sticker.mask = noteMask_mc;

Tweener.addTween(noteMask_mc.mask_1, {y:-540, scaleX:2.5, scaleY:2.5, time:10, transition:“easeIn”});
Tweener.addTween(noteMask_mc.mask_2, {x:255, scaleX:2.5, scaleY:2.5, time:10, transition:“easeIn”});

has anyone else run into this? And has anyone found a solution?

Thanks in advance
