Hello! I try to load a 3DS-object but the object will not be visible at all. I have also add some light but I still can't see the object.
On each side where the 3DS-object should appaer I have added a Cone, just for reference and se if the light works. I'm not so good at 3D-studio so I downloaded a object from the Internet so I have something to test with. That object can be found at: http://medlem.spray.se/fredand44/questions/girl.3DS I also have an other one that I have developed my self at: http://medlem.spray.se/fredand44/questions/test.3DS But my own object doesn't seems to have any Shape3Ds? Perhaps any one could give a hint about that as well. I use the Import3DS from: http://www.j3d.org/utilities/loaders/3ds/mulder.html to load my objects. So if you would like to test this I think you have to download it. So if any one could give me a hint I would be most thankfull!
