i just started DECIDE'S coming of the Horde campaign, and i wondered how u edit the background (or foreground, for that matter) of the campaign screen (like i want to replace the night elf archer in the forest with another unit...can i do that?)
They are .mdx files, so you would have to edit them in a model editing program. That archer is probably two or three times the polys of a normal archer unit, and has multiple UVW maps. Replacing it w/a knoll will take some good modeling knowhow.
