Glad to hear you got it working.

I did manage to take a look anyway, and I think you stumbled across a bug in the way the the input nodes might have been disconnected from the solver, but the “Include” toggles were still instructing the solver to use those items. The solver may have been erroring out and it looked like it wasn't doing anything. I've committed a fix for this and it should be available in the next daily build.

The Target Strength parameter had to get up in the neighborhood of 30,000 in order for the tissue to not fall away from the animated target position.

When combined with a painted mask for the targetstrength, ie:


The solver produced this:

Without any internal bones or muscles, the tissue is only constrained where the mask is non-zero.

By adding some very simple bone geometry, it's enough to hold the bulk of the tissue in place:
