There is a hard way, you have to make an app that does it for you. V3 is an interpolated V2, the directly matching verticles can be transfered directly by asigning the correct delta number to them, the morph values for the interpolated (new) verticles have to be calculated acording to their placment to the non interpolated verticles in the original V3 model. V3 to V2 would be much easier. Just drop the interpolated verticles and reasign the delta numbers of the matching verticles. Staale
