Hello Teyon, --- Yes I know, and I actually do edit my weight maps in the Pose Room all the time, using the Joint Editor. --- The reason for my heads-up: --- What if you need to create an additional Helper Bone in your already mostly developed figure?--- Dang!--- I understand the reason for the warning message when entering the pose room, but as long as I do not touch the present grouping, everything will be fine (all morphs still working) after I leave the Setup Room. Less the nuissance that ALL hitherto "hidden" parameter dials are now visible. --- I don't think that this is necessary, and probably only requires a very small change in the code: >> Remove ALL occurrences of "hidden 0"<<, and just leave the parameter dials' "hidden/not hidden" status as it was before.--- Not too difficult, I suppose.--- Cheers
