I created a quadruped character, and added ik bones to the legs, but the problem is the knees start clipping when it bends. i tried to see if changing the weight paint would help, but it just got worse. How can i make the knees bend softly, without clipping?
I've tried the following things and it seems to work:
Enable the Armature modifier's Preserve Volume option
I've added an edge loop above the joint:
- I've segmented the small bone:
- I've extended a bit its influence upwards in Weight Paint mode, use Mix, Substract, use also the Blur brush:
- And I've extended a bit the influence of the top leg downwards:
A try with 2.79, I 've added a Pole Target to make it bend correctly:
