drawMasks won't use alpha in experimental branch

[naychrist]

hey there, love this addon - use it all the time.

need to have auto skeleton tracking so am using experimental branch. also need masks but in the experimental branch it always draws white for the transparent pixels, even after ofEnableBlendMode(OF_BLENDMODE_ALPHA) or ofEnabelAlphaBlending()

am I missing something? Also, it would be great to have a function to set the colour of the mask to something other than black.

cheers, nay
