dan, he talks about instances. it doesn't sound like your exporter from max (or whatever) automatically exports instances. or does it? of course instances take less space, loading time,... than separate models.

maybe he also doesn't have a modeling program were he can do all of this.

ulillillia is right. only wed doesn't support scaling non-uniformingly. per script you could do it. or per editing the wmp with a text editor.
