Blood Raven(Sylvanas Skin)

[Antar36]

I need skin Blood Raven (Sylvanas). I need adding bone mask from Hero archon (Hero_Archon ) to base Sylvanas model (Dark Ranger or High Elf)
Maybe I could do it myself, but I need help with geoset.

Edit:
I'm trying ripp model from HoS. Unfortunately, I can not convert the m3 file. using jm2converter. Can anyone do this at home?

Thanks for viewing.
