I have a Morphing Fantasy Suit conformed to a Michael 2 figure.  It doesn't quite fit the physique of the figure so I tried to do some minor adjustments with the morph tool.  For some reason, it makes no changes on the Chest, RCollar, LCollar, and part of the Abdomen, all of which are of the same material by the way, a simulated armor.  It will affect the lower part of the Abdomen which has the pants texture on it.

Those body parts are not locked.  The figure is not locked, just conformed.  Why can't I morph the armor parts with the morph tool?  Thanks for your help.
