Thank you Dwayne! I did have the origins local to each object, but did not think the proximity of the links would be that much of an issue. Thank you for the tips!
Scaling it up definitely helped overall, and I ended up ditching the bottom weight so it would make more sense on my “track”. The idea was that it would offset the plank atop and make it tilt, but between having the links+weight behaving a little weird, and that I couldn’t figure out how to make the plank behave passively until the weight would tilt it… I ended up just checking “animated” and added two keyframes.
Overall it’s quite impressive how much we can accomplish with so little keyframes. I have a course with 10 to 14 steps going on and 4 keyframes total. Amazing!
