Shaking problem when collision

[josemendez]

here is the solver and obi soft body and obi material setting.

we have a monster in Full body volumetric softbody.

When use a cube(weapon) to touch the monster, the touch area of the monster shaking ver fast.

Not sure if it's the cause, but your collision material parameters don't make any sense. A negative distance for sticking is usually not what you want, and rolling contacts on softbodies are also not something you'd usually use. Set the stick distance to zero and disable rolling contacts.

Also in your solver you have a shock propagation value of 0.66, that's extremely high. Shock propagation is only used for piling lots of objects, and even then quite low values are typically used (eg 0.01).

You have surface collisions enabled in your softbody, for full-body volumetric setups this is typically a hindrance rather than a benefit because of the huge number of simplices that will be generated. Disable them.

Let me know whether these changes improve behavior.

kind regards,
