Okay, I got the mask shape to paste into the Brush Position property.
There’s still one problem, however. When I paste it, the brush position goes way the heck off to the corner of the comp. It follows the shape of the mask, but for some resaon, it’s way off in the corner. It’s like it’s following where the mask would have been if I hadn’t scaled down the layer to comp size or something.
Any ideas?
