@ianr Actually my experience has been that the "Body" morphs don't work at all but the individual body parts e.g. Neck, Chest et al, do work. However even when I would say, tweak the PBM Young parameter, the entire body was morphing young as well. I'll be trying this out on Sickleyields cloths for V4 which have morphs that don't work at all once it's conformed. At least not for me. The morphs do work as long I don't conform it to the body. Luckily they are chest and hip cloths so parenting was the savior there.

@Miss B I like information threads. Hopefully it helps someone else in the future.
