Unscripted - good idea, but because it is being looped about 150 times, I was hoping to avoid the layers/task for something that should be relatively simple. Might have to do so if no other workaround, however. thanks.
IamSam - I have a character waving, which takes about 12 frames. For the rest of the animation, a lip sync, it takes about 1800 frames. I wanted to loop the 12 frames in the animation timeline so that it is continuously waving for the full length of the lip sync.
