The dynamic spring is interesting but the problem I have with it is that it’s completely up to the system with no manual adjustment (and always on ones). There should be a way to do the movement, then bake the automatic spring (as keyframes) so that you can manually adjust and set to twos.
Follow these steps
step 1
Go to timeline. find your dynamic spring
hit the + to open up the properties
find Active
Key value 100 on the frames you want. yes use the “create keyframs on” to put on 2’s 3’s. whatever you want.
step 2
Go to the layer Properties
below Active is a box
Match Animation on Active Attribute, check it
