Sub Wrap
Detach / Attach
Detach and re-attach the SubWrap driving cage when you need to adjust the cage shape.
Use Detach / Attach when the SubWrap driving cage needs shape edits. Detach the WrapDeformation before making cage adjustments, then attach it again when the cage better matches the model.
With SubWrap, deformation cleanup is usually done by adjusting the shape of the driving cage rather than painting weights directly.
Keep this step focused: detach only while editing the cage, then attach again and test the deformation before continuing.
