Thank you so very much for this script. I would never have thought to check for the os !!! I'd have a final request, if it's possible : Is there a way to 1-check each part of the dress I just modified with the magnets 2-set the morphs to 0 (and also the dials related to already existing magnets in the dress before the one I added) 3-spawn for each a new morph target, called "conversion" for instance 4-delete all the magnets (save those that were already present) 5-set all the "conversion" morphs to 1 (and also all the dials related to already existing magnets in the dress before the one I added) I know that the parts between the () would be quite tricky to make (I have no idea how I would do this), but even without these parts, it would be great to have the rest. Thanks again for your help. sylvain
