Skinned softbody jitters when still

[josemendez]

Heya!

We're currently facing an issue, where a softbody jitters a lot while being attached to a bone that is not moving.

I followed this tutorial to set everything up: https://www.youtube.com/watch?v=75AQT_Ls8fA

Here's a video (slightly nsfw warning) https://puu.sh/IFn0A/47b6af4ecc.mp4

I've tried to add smoothing to the solver, but it does not seem to change anything at all. Turning on interpolation makes everything into a jumbled mess. This also happens when I turn interpolation on outside of playmode. Is there any obvious mistake I might be doing?

Hi there!

Is there any collider nearby that the softbody might be colliding against? Looks a lot like what happens when you attach an actor inside a collider: the attachment wants particles to be inside the collider, and the collider wants them to be outside. Since this situation is impossible to solve, the result is a lot of jittering. The solution to this is to use collision filtering to stop the offending particles from colliding with that specific particle.

Let me know how it goes,
