I am experiencing a problem in my attempts to utilise the 'Destination Out' effect. (Or, any other effects for that matter)
All I am attempting to do is cut a rectangular shape out of another rectangular sprite, as such I am simply using a coloured square as the sprite image. Instead the sprite simply turns black, not interacting with the sprite beneath it in any way.
Strangely, the blend mode example project seems to be working fine.
Is there something I am missing here? Should the sprite image depict something more complex like in the example file for it to work?
