[HELP] Model loses textures during export from 3ds max

[Henriksen]

First off I've told you several times that they MUST be in .dds to work. JPG will NOT work.
However that is not related to unsupported shaders, are you using max standard shaders or are you perhaps using Vray or MentalRay shaders? Only Standard materials will work.

And why is there two materials? I can only see one texture being used.

Yeah I get that they should be in a .dds format. When I open the .jpg file in gimp and export it into .dds it still says .jpg. And I don't know what kind of shaders im using, I am new to this whole modeling stuff.
