Splits wireframe

Left: all forces but length. Loss of detail around abdominal muscles
Right: all forces. Better preservation, minor loss

LBS ROM

A little difficult to compare due to video size. Will crop these so more of the mesh is visible on each side without so much filler space in between.
Left: without forces
Right: with forces. A couple of frame-to-frame artifacts (slight bulging on the arms), but also better volume preservation in the bends.

Force combinations

Length force only. In this LBS pose, the mesh has 14% less volume than when it's in bind. After the length forces are applied, the mesh has 3.74% less volume than bind.
