Alternative to BlendMode.ERASE on windows platform?

I’m trying to do an inverse mask on windows platform. I set parent object to BlendMode.LAYER, and set the mask to BlendMode.ERASE, but it doesn’t seem to work. So I guess it’s not working, as document stated.

So, anyone ever found an alternative for inverse mask for GPU rendering?

It is not very difficult (in theory) to do this with GPU rendering:

(look for maskInverted here)

Support for BlendMode.LAYER + BlendMode.ERASE is not supported yet in the OpenFL renderer… but it could be! Happy to discuss if someone wants to help implement this?
