thanks for your input!
I thought of this myself. Removed the binary bit from the files and used them text-only versions without success.
It has to do something with the structure of the metadata files, as Jorge Tizado pointed it out for me.

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 ?
