A lot of promos seem to use older hair props parented to the head. Really boils down to does the hair prop have enough movement morphs to avoid pokethroughs in the shoulders/etc after Genesis’ head/neck is posed.
Looks like I’ve got Saphire Fox in my runtime. Haven’t used it in ages though. Just noticed that it contains a “Universal” Hair Prop version as well as the V3 SP3,and Jessi versions. Guess I’ll try loading the “Universal” one onto Stephanie 4, (since I don’t have S5) and see if I can adjust it to look like the hair in the promo.
To everyone who responded here. Thanks for the help.
