Hi! I am having issue with a setMask that is only working inconsistantly. The content it is masking is a looping animation created with actionscript and the parent movieclip animates with a tweening plugin. Perhaps this is all too much movement for the mask to keep up with?? Any hints/suggestions would be much obliged!:sonic:
