N64 rips: no texture but shiny?

I did more VRML rips, and came across something new to me. The resulting model had objects that had no texture applied to them, but they were shiny and metallic-looking. When I export to OBJ, they lose that quality and become white.

Example

Like the little knob thing in the lower left-hand corner of the computer. It's weird, because some of those things weren't even visible in the game when I ripped the scene.

What to do?
