Fixed an issue where when "Sim Enabled" is unchecked, and "Use Guide Mesh" is checked, the clothing mesh would be stuck in place
Fixed an issue where legacy smoothing will make mesh disappear on even iteration values.
Added smoothing (Legacy) for guide mesh. Iteration can be adjusted under simulation tab
Mesh boundaries are excluded from smoothing
Added simulation passthru for hard pinned vertices in Guide Mesh Sim. Now if a clothing vertex has guide mesh nodes that are hard pinned, and their weight sum > 0.8, the clothing vertex will use its bone skinning result directly
