Hello,
I try to use the the new muscle sops and to get the muscles more attached to the bones I tried to increase the "tangent stiffness" in the "Muscle Constraint Properties Vellum" sop but it seems to have no effect. I think internally it uses the attach constraint, but it behaves not the same way, as it does in the standard vellum solver.

quick demo file is attached, and the version is 19.5.534
thank You

A fix for this issue has been recently been made. However, unfortunately, it may not be available until H20.0.
MuscleToBone Tangent Stiffness should now be working correctly as of Houdini 19.5.585.
