Hello dear community,
I made a post on the answers hub regarding this spring controller jitter - UE4 AnswerHub but I thought Id also look into the forums to ask your combined wisdom.
There seems to be an issue with animBP spring controller and global translations of character. Im using it to add breast physics to my character. Its already behaving much much nicer than the physicsAsset. So what I do is add spring controller to those joints instead. But the problem is that when the character is moving, or standing on something that moves, the spring bones start to jitter and glitch very badly. When walking or running it isnt that much noticeable, tho its still there, but in this case (see video) its really obvious that something isnt been calculated right. I tried setting substepping, but that didnt affect it at all.
Here’s a link to a youtube video I made showing the issue and talking a bit about it.
Any Ideas why this is happening and how to prevent it? Id also like some more in-depth documentation about nodes like the spring controller, maybe an api doc with technical data and physics/math insight?
