Importing OBJ format doesn't load MTL c...

    Latest code from SVN repository fails to load MTL materials associated to OBJ
    files. The import works correctly, but face colors are wrong. Old BETA 1.30
    2010_10_08 and official 1.2.3 versions did work correctly in this regard.

    I can provide sample OBJ+MTL pairs that fail to import colors correctly in
    current development version.

    I have built a custom version using "import_obj.h" file from version 1.2.3 and
    I get colors right.

    Yes thanks, can you provide an example file?

    Nevermind, I updated my codebase from SVN to get the old code back and I found
    out it's working ok now.

    But please have a look at my other post about U3D, I've spotted the bug and
    it's a very easy patch (just move a closing brace in the generated IDTF).

    Well, this is starting to become a little weird. I've updated my sources from
    SVN again and rebuilt.
    Now the OBJ+MTL import shows incorrect colors again!

    Since it's a quite large example (1.8MB zipped) I don't know how to post it,
    bug tracker has a limit of 256KB for attachments. I'll try to see if I can
    reduce the size.

    Ok, I found out that menu option "Render > Color > Per Face" does display the
    correct colors!
    But I never changed that and it was set on "Render > Color > Per Vertex", that
    shows wrong colors.

      I also found this as a solution for my problem.
      Do you know how to have the menu option "Render > Color > Per Face" as the default, such avoiding to set it again and again?
