I have a similar suggestion: clothing items can be grouped by material. Is it possible to add vertex groups or material groups to skins for the purpose of grouping?
I have a bug to report. If the toggle is on for "Save Sim Data", which it is by default, but the item has no sim data. And you hit save. VAM will hang. And you lose your work. @techwoof could confirm this on their end as well.
Suggestion:when selecting verts on clothing, after selecting some verts, a reverse selection function will be so useful, hope regguise can consider to add it , this is definately a must tool for clothing creators it can meet the needs of basic and advanced users all by one!
