So, I finally decided to give something back to you guys after beeing a leecher for a while.
I have patched together ScDK's blood elf model with a NiF -> BeF race swap. Everything is working perfectly, even with nude mods if you like that. :yuck:
I also do not know if something of the contents is removable (I am lazy), so the file is quite large.

P.S. Oh yeh, the npc skins are still night elf, but I have not found any working raceswap mod yet.
