you want the max script and 3DS max has a 30 day trial so do as many as you can while you can.
Or I already converted every model in the game. I converted to 2 different formats. FBX will import all the mesh points (weapons, exhaust, hangars etc) and OBJ imports the UVs.
One thing the script does improperly is it mirrors the models so I had to write a script for XSI that flips the model and the mesh points. This is only really needed on the TEC ships as most all the others are the same both sides.
What models are you looking to do because I will soon have them all saved as finished scenes ready for XSI.

Theres a few different versions of the script around
The first image is the original import. Notice the KOL writing is backwards

After flipping in XSI. Click the ship to save the scene.

After you have the ship in XSI, COPY the textures from the root dir into the projects Pictures folder.
