Has anyone ever tried using paintengine on a mask channel?

Wouldn't that be so cool, a paint mask, then you could, say, do a dry brush based on the mask, then invert the mask and so umm... ahh.. pallette knife!!..

<oh boy, Fluffbutt wiggles his furry kitty cat tail and runs of to try it out!!!>

Well !!!! THAT was interesting!!

I also found another really good fun thingy to do - load up the luminance of a picture as a setting, do one PE preset, then invert the selection, and do another PE preset

*** it's advisable to feather or gaussblur the selection before doing the 1st preset (the inverted selection will still be feathered)..

This gives some really lovely impresssions...
