Simulated Bones are Jittering

Development Character & Animation

i want to Simulate some bones of a Character (hair, cloth parts) but every time the frame rate is breaking down or when the char is moving to fast, the bone chais ar jiggeling around and breaking apart.

i tweaked with the dampening and stiffness but it its sill raging around…

and another thing is that the simulated bones are working like expected, but in game the simulated bones dont collide with the not simulated bones, why is this so?

is there no way to fix this

Hi DarkneZ,

The issue you are experiencing sounds very similar to the problem described in the following link:

Please review that AnswerHub Post to see if that solution is applicable to the issue you are experiencing. If not, let me know.

Thanks

Depending on how bad your framerate gets you may want to turn physics sub-stepping on.

i have problem with simulated bones on attached skeletal meshes.

and it there as option i have to setup to get the same results like in the phat tool? the simulated bone/collision object are penetrate/ignore the not simulated collision objects.
does it make sense for you??
