I can't give any details, but I know of something that will be VERY useful to fit hair to G4... and it works GREAT with Guy.

For the time being, the best bet is to scale M4 hair to about 142 (from 100), Then use the Y and Z trans to position it. April's newer hair has adjustment moprhs that REALLY help with fitting the hair on the sides and the temples too.

I'll try and do some hair poses for Guy for April's more recent hair early this coming week, and do it as a bonus freebie.
