Conversions I've tried so far are: M2 to M3 Dork to M3 Hiro to M3 M3 to Hiro V3 to M3 Posette to M3 PT to M3 Laura to M3 M2 to Hiro M3 to Matt M3 to Luke All of them worked, but sometimes are there are problem spots. Shoes, crotch and breast regions for instance. Adult female tops to M3 is tricky to make natural looking. Oddly, the unimesh seat-of-pants region changes a great deal betweem M3, Hiro, Luke, David, Matt, and M2. You'll need to fix it by hand with a magnet. I haven't tried converting to Apollo, but I know long sleeve shirts can be tricky because Apollo is not in the default "T" zero pose. I highly recommend WW. Best add-on to Poser you can buy, imho. bB
