I've noticed that the MTL files have some form of binary info at the end 
(last line). This keeps several text editors from opening these files. 
When I open them in vi and erase the last line, everything is fine. I 
don't know where that line comes from.

Maybe that's what's keeping the module from reading them correctly ?
