Thanks,rube.Problem is I baked a rigid simulation I did in Maya and I want to reverse the frames.Doing it that way is difficult because of the huge number of frames (200 frames)the viewport lags heavily so I can 't scale it that way to precisely -1.I find this very weird,why Maya doesn't have an invert or reverse frames.
Not quite,like in Flash if u have a ball that tweens forward,u can reverse the frames on the timeline so they tween backwards when u hit the play forward button. Does maya have a reverse keyframes like that?I know u can switch the keys in the graph editor if u have two keys but this will be difficult if u have like 40 keys.
