For a character based model : http://www.model-changing.net/tutorials/article/40-how-to-create-custom-npcs/ Non character based model : http://www.model-changing.net/tutorials/article/42-import-creature-from-catamopwodlegion-to-335/ just look after the extraction part I hope it's what you need
I found it too in my old computer (we find a lot of things in my computers !) I don't really know who wants to use it but it's here, if you are taken by a mystic Egyptian passion ! Creator : Dunno, this patch is really old.
I found it in my old computer, I don't really know what it contains but I'm sure it was made by SirFranc AND Stromgarde is in it, I'm 100% sure. This patch is useless for me and I know Sirfranc allowed this share, so I give it to you, maybe you'll find some interesting things
