I am gonna do what you did XD all you have to do Is Get the iaso rin,Get rid of the bones and stuff,and keep the hair bones and stuff and then take off the hair on project diva miku and get rid of the physics an bones,ANd then Get the iaso rin hair in there,take off those white thingys ON THE HAIR THEN put textures on it then BOOM!!!you have a WILLY AWESOME MODEL
Do you have a media fire account? If you don't, get one. Once you do, compress the folder of the model, in this case of that uber cool miku, and upload it. Best to put a password on it. We will note each other about what models we have and what we want. Once we figure out what we want we not each oter the link fo the modle download, but we keep it secret!
