Further to my previous post, I have managedto use the supplied textures though I dont really know what is what so it has been a bit haphazard,.
Before you start altering anything try to use the original textures that are supplied with the model. I noticed that you have tried every combination of specular, diffuse, difference, bump and ambient without much success ... look at the three textures weapons, hull side , and hull to see where I put them. When you need to apply textures to the model you will need to un-group the model before you start.
Try to get .obj files if you intend to keep downloading these sort of files as they are far better than .3ds, they also have the advantage of a .mtl file which lists the textures used.
