When creating models in 3d studio max to import into UDK the file format of the textures used is extremely important. I had been working with PNG file formats. I would unwrap UVW for each mesh. Then create a UV map for my mesh and render a UV map in a PNG file format. I then would import my PNG file into photoshop and texture as appropriate. After that my PNG texture would be applied to my mesh in 3dstudio max, which always worked fine. I would then export my mesh as a .FBX file which includes both the mesh and the textures. Next I would import my mesh into UDK as a package. After this one of two things would happen. Either UDK would immediately crash or else the model would import with no textures attached. After a lot of trying and trying again it became clear that the problem was the texture file format. I then began saving my textures as .tga (TARGA) files and the whole thing worked perfectly with my models being easily imported. I still have not been able to successfully also apply a bump map to my meshes.
