Hi,
I have been working with several weighting and topology arrangements and still get a crappy volume loss on the knee when it is at an extreme bend.
Has anybody had luck with using a second joint as a mass holder? Like a leaf node that is a child of the knee but helps box out the knee in the extreme angles?
Any other advice, I’d rather not add to the points of articulation already there in the skeleton.
thanks,
Brian
Corrective blendshapes, two-bone knee set up, or a leaf bone that has it’s movement tied to a dampened down ratio to the knee, or use a set driven key tied to the knee’s rotation so you can plot out how much it moves.
That’s all I got :T
Knees- The initial joint placement I find is very important…many times it is not in a good spot for deformations.
After that a second helper leaf joint that rotate/translate based on the bend or more stable change in distance or angle between the bones can drive a Driven key of the joint to correct the shape.
Can you post an image so we can provide better feedback? A before and after shot of shaded wireframe, if possible.
