Hi Jack, thanks for replying, I also sent you a msg since I can not upload a fla file here I can send you an example if you need it. But basically I have very simple movieclip, I skew it using flash IDE, then grab the details I need to do EXACTLY the same with a transformMatrix, but it skews in a weird way. It seems like its fliping and the same time:
TweenLite.to(mc, 9, { useFrames:true, ease:ClassicEase.ease, easeParams:[0], transformMatrix:{a:0.466400146484375, b:-0.884552001953125, c:0.884552001953125, d:0.466400146484375, tx:-47.05, ty:-38.5}});
