Ok.. many people have this problem, guy..
Caligari's tools export objects in their own measure units..
Be careful when you configure the exporting settings..
I think that in Caligari TrueSpace 3.2 this option is already available.. Change the unit into something like meters, kilometers or whatever other greater values..
Or try just to superScale up the objects in the editor before exporting.. RightClick on the white arrow button (in gameSpace it is on the bottom right of the screen) and change proportionately the _x,_y and _z scales... Then export..
Or make this "scale object 1, 5000,5000,5000"
scale object [object number], [_x%],[_y%],[_z%]
Good luck
