Hi Kevin, the link to your preset is dead. Can you please re-link it? I am having the same problem. I used the expression you wrote on the boatd “[Math.round(position[0]),Math.round(position[1])]” but now the crawl jumps every so often. It goes 2 pixels up, and from time to time it goes 3 causing a “jump/stutter” in the animation. I would greatly appreciate it if you could repost your preset.
thanks!
