@bigsmileling what program are you using?
I use 3ds Max 2016 to adjust and position of the hairstyle, and zmodeler3 for textures and rigging.
I can make 2 mesh with 3ds max or attach the bow with the hairstyle, I have tried today creating two mesh and attaching them in Zmodeler, but when using OPENIV to attach the internal textures it gives an error.
Right now I have 3 files:
A: 1 bow
B: 1 haircut
C: 1 haircut+bow together (In the same model, they are together)
I don't know if I have to use A+B in Zmodeler or just C.
