I've been at this for two days. I've seen all those God-awful tutorials where the guy mumbles and clicks shit as if anyone but him knows what he's doing.
The help files are easy enough to understand and I've tried every method I've found.
The problem is the masked area shows those white and gray checks in the field and you'd expect that area to come up transparent but it never does, it just turns to white.
So this is the character. I want to snip off the bottom of her skirt. As seen it's always just white, never transparent.
