If you add David then remove all ik and zero the figure, then add the m3 clothes and scale till it allmost fits, then use the joints of the clothing to try and improve the fit (never move any David joints) then fix any poke through with magnets.....once it fits delete david and export as obj, now on the last window you get (can't remember what its called but its the one with things like, include body group names, and the like) check ONLY the top box.......you now have an obj ready to plug into a cr2, so use a David cloth cr2 to swap the geometry with or use something like PWizard to create a cr2........Steve
