I was wondering if anybody was interested enough in making a westwood 3d (.w3d) exporter. This is somewhat used in the SAGE engine (which is basically 3d all Command and Conquer games, Battle for middle earth RTS games and command and conquer renegade).
At the moment the only way to export things to .w3d is through gmax and the renx gameset or 3ds max (most recent versions before 09).
Unfortunately it is further complicated by the fact that the .w3d can have several different settings (at least for CNC renegade it can)
here is a link to a page that may have some useful information.
