I'm having a strange problem with a couple of my characters joints. Specifically the knee.


The knee bends okay, and the calf and chin move correctly, but when the joint starts to reach the extreme portion of its angle, the part of the mesh that's attached to the thigh bone starts to stretch.


how do I prevent that stretching?


Hopefully the attached video will be a better explanation.


I've tried setting various thigh bone values and nothing seems to work.


thanks

Maybe there are a view vertices from the knee wrong attached to the lower leg bone ?

Nope, I looked at that. All the vertices are attached to the correct place. It's sort of hard to see in this image (the blue points are really small) but it shows me that all the points on or above the knee padding are attached to the thigh bone, and all the points for the sock and below are on the lower leg bone/foot.

Bend the knee until you see the points come out, then edit the muscles, click the bone above, (like you've done in that screenshot of yours) and below the joint, and also the joint itself, find the abnormal points, and get rid of them

Well, that was sort of the question. As near as I can tell, there are no 'abnormal points'. they're all attached to the bones they should be. Any point attached to the knee joint shoots out when the knee is bent so I can't put any points on that.


Editing the muscles doesn't have any effect.
