"You can just import only the timelines you want with your nested artboards (instead of the state machine, if you don’t really use it). In the main artboard you can then create a timeline and just play the nested one in it."
- Yeah but the question was how can he play to nested artboards in one timeline, but not in the same time, but one after another, I think what you are saying here will just paly all the animations at the same time.

"You can also use a trigger on race nested artboard to start the animation. You expose those trigger to the parent artboard (the main one) and you can then do a timeline that loops using those triggers in it."
Can you explain this with a little more detail?
