sorry i feel i may have put this in the wrong section.
basically you can use tweenLite to:
TweenLite.to(mc, 1, {alpha:0}); followed by
TweenLite.to(mc, 1, {alpha:1, overwrite:false});
in order to fade in and then out of alpha,
i was just wondering whether there was a set "autoAlpha" which faded to a set amount i.e. 0, 0.2, etc and then back to 1 automatically.
sorry for the confusion
