The position animation does happen with lerp. The position timeline goes from 0-1-0 over 2 seconds.
All cubes move with the same timeline, I just offset their position with changing the playback position with a 2nd timeline (that goes from 0-1 over 1 second)
It’s a dynamic rig, so all the cubes can stay still at position 0, start moving equally (which means no delay) or move with a random variation (which means a different playback position for each cube)
I need all cubes to start moving at the same time (so I can’t activate the timeline one by one with a delay node).
Hope I’m making sense
