at the moment, i dont know exactly how to export animations, UV's and vertices at the same time. there are some scripts i've found that dont really work. i have been searching for a way to do this for months. almost a year now.
the only way i found out to export UV's and verts is to use blender to export as the format, .OBJ, then have a 3dsmax user import the obj to 3dsmax 5, who will then export to MDX/MDL.
ill keep you posted.
as to tutorial writing, anything i stuck at you wouldnt be half as helpful as the stuff on blender3d.org. trust me.
saving a model? eh...file>Save as? or do you mean wc3 models. either way you got it.
