First is just give the 3ds object a texture like the ground so you can see the shape of the mesh. If that works well then remember the cube is solid and the 3ds texture is not. This is why I love procedreal textures. Sometimes you get the weirdest results. You just fight and fight with them. When it's like that I use pictures mixed with materials. Your using math to make a cage now your applying that texture to not a solid cube so the math is different. Make sence? You get weird results.You can texture it no problem in Vue cause I do it all the time. You don't have to map it in a different program although that gives way more control.
