@odf,

I installed the v0.9.126-21-gdec94b4.zip, but the joint spheres (sphereMatsRaw) are missing and disabled for jointX. The joint spheres are an integral part of the way I set up that joint, and I don't think it works well without them. I have moved on a bit since I first posted the joints. I have changed the X orientation of tongue2 to 10.0, and modified the outer joint sphere for jointX. This seems to give a better thickness to the tongue tip, which was too thick when bent up, and too thin when bent down, and also gives a better shape under the tongue. I have also added a little bit of 'bulge' to jointX.

I will attach my latest settings for tongue2 in my next post
