lol . That is pretty cool that you are making an animation system, does it work well? This kind of stuff can also be fun for adding modding support for games, so players can easily merge ingame models & attachments and than export/save it. (since .obj can also be used through ent_create) I only dont know if animation is supported for .obj, thought not iirc.

I just got an idea to compare the .obj text exported by this code with working .obj text exported by model programs, that should give me some clues. (suprised I hadn't thought of this sooner)

Also this seems like an interesting article (http://paulbourke.net/dataformats/obj/) I am going to dig in a bit
