Why would scaleform combine masks on separate movieclips into one?

Question

I'm working on a project using scaleform gfx 3.3. On a 3Di layer, a bunch of different movieclips are created. Some of them have masks. What appears to happen is that all the masks are combined into a single alpha channel. Each component masks properly when they aren't overlapping, but when they are, they share the mask space of the larger component.

Is there a way to force scaleform to respect their masks individually?

Answer 1

Have you tried moving the movie clips to separate layers and retesting? FYI, masking support was greatly improved in Scaleform 4. Is there some reason you're still on 3.3.?
