other differences are subtle mesh morph modification in hip and left/right collars, as well as reworked "materials" groups for AD as such, there are some clothe specifically designed for AD in mind that doesnt fit perfect 100% with base MD, but the CR2 upgrade for MD provides two magnet poses that morph it back to match AD both MD and AD share some problems, that were never solved sort of slight misplacment in genital area, hands phalanx that are sometime horrible to pose, and the fact those two products were lovely, oen of them free, were decently supported since their start (i mean, for an outsider brand new figure trying to raise an hand for not drowning in a sea of vickies) but Aiko3 was the bell of MD/AD requiem :( still, i like MD for it's versatility and low polygon, fans and Maya made v2/v3 uvmapping as well, some cloth conversions from v2 stuff are availab,e some software exist to convert v3 clothes for her too i think it is a good alternative, still and desserve some support with tenten and an an , mayadoll is one of the few realistic asiate outof the box i ever saw (once saw aJAV movie with a girl that.. OMG... was a near clone of MD :)
