Hey -
Adding a Linear interpolate (Lerp) node after the timeline should give you the smooth transition between the start and end points you’re looking for. Use the current position as the A and an add node (your starting position + how much you want to move) as the B. Then you just need to set your timeline from 0-1 in the y-axis and the amount of time you want the Lerp to take in the x-axis and plug that into the Alpha of the Lerp.
Cheers
