Good day! First of all i wanted to thank you for such an amazing rig system, it is such an quality gift to a whole blender community. I have rigged the character body with significant changes to the density of the cage since proportions of the character is very unusual (very tall) and i do not have a good result with hands and legs no matter how accurately i mapped default mdef cage, but happily i overcome that problem. However upon revisiting the face which on first pass i deemed as “good” now look… weird to me. My character is a realistic type (not exactly in proportions but overall style), i don’t know how to properly explain, it’s seems that reach the “uncanny valley” effect. Mouth opens and corners moves too much. Mouth upper corners movement looks unnatural and smile looks goofy, when upper part of the lip moves too much. There weird behaviour (or at least it looks like) from bendy bones, when lips are closing in. Also for some reason corner def bone weirdly was popping out so i needed to manually adjust it after binding. Fix joints function do not solved anything. Mind you, im completely examined your tutorial (which is great) and used all techiques as described: Skinned with no autonormalize, overlapping the weights against horizontal and vertical def bones, adjusted actions so mouth moves more naturally (like when corners moves in closer to the jaw). I even examine Vincent character, removing all smoothing and drivers to understand and know what exactly should i paint. Setup corrective smooth, technique of blending smooth groupes and paint them accordingly. But still overall result is far from pleasant, which i understand that it 100% might be my fault. Im spended like 3 weeks on overall face only and i just kinda dissapointed with bendy bones, especially when it’s advertised as easy to use, to the point when this in this https://youtu.be/4iBkwVQHRzA?t=570 tutorial which is just using positioned bones with automatic weights looking better and realistic, so i just thought to abolished it all together and start from scratch using standart approach of bones+shapekeys.
Maybe im looking in wrong direction, can you please help me to understand what i did wrong? Does this system not suitable for realistic characters with not so much exaragated mouth movements? I already adjusted actions and constraint to fit realistic character. I will link cleaned blend. file if you wish to look, for some reason despite all cleaning it is still too big so i loaded it to another host. https://gofile.io/d/QvUckI
