You need a program that can accurately export to DTS, there is only MS3D, Blender, 3DS Max and Shaper, but Shaper pretty much is MS3D and costs money.
Are any of them free, by any chance? =3
Indeed.I can export quality models to .dts from a sketchup save format if anyone needs it. Give me the sketchup and I'll send you it back in .dts. Although I reserve the right to say no to rubbish models or people.
You can't export directly from Sketchup to DTS for a start. You'd need an intermediary program between sketchup and torque like Milkshape. However you can't export as .obj from Sketchup without buying Sketchup pro, and milkshape wont import any formats from the free version of sketchup.
