well I have newer tryed this but in the menu there is a butten called import i think. Amd it says 3D Studio when you move your courser on to it. Try that, or maby you van yuse open, and change thi file type to 3D Studio (*.3ds). maby that will worke but as I said I Have never tryed this before this is just try it. that is som beuteful models but I have heard that models whit a to big poly count can't run I OFP or somthing like that. If it works then good and if it don't then sory.
Good luck. STGN
