I need to add a sequence that comes before another animation sequence. My problem is, the existing sequence has got several objects in motion. Is there a way to move all of the timeline markers in the project window further to the right to create space for the sequence I need to add at the beginning? Or is there a way to expend the timeline towards the left?
Keyframes can only be moved on one Timeline at a time. There is no way to select everything and move them all at the same time. You'll have to adjust each animation sequence by it self.
It may be easier to make a copy of the model and erase all animation then animate just the new beginning sequence and render it separately from the other piece then combine the two sequences post render.
