Does V3 go from pink to white when you click the MAT file? And are you using the ones in !Mat V3 or !MAT V3 MapsHi - it's the latter you want, either !V3MakeUpHi or !V3NaturalHi. Only the texture files with names ending with a 'B' need to be converted to BUMs for P4 - the rest are straight textures and work as jpgs.
