Erm, do you have the latest version of BRRES Viewer? It can export OBJs.

And, the only two things you have to mess with, are the file format drop down and the "Flip UVs" check box. Noesis does not produce MTLs. It does OBJs in a simpler way, and they still come out fine.

EDIT: Oh, and you have to have .OBJ, with either a .DAE or .SMD with it.
