Well after 3 days of trying everything I could do by hand, I just happened to stumble across this little gem a few minutes ago which has solved my biggest problem with the massive material import...but has also given rise to others which can easily be fixed with a macro script:
http://meshlab.sourceforge.net/I have yet to study how it fixed it, but it appears my material list file was definitely correct...On the other hand, the original object file will need to be scrutinized and compared with the one that was generated by meshlab...
Perhaps I spoke a little too soon here, but maybe this will help others...
Btw, my tool of choice for automating repetitive tasks is Workspace Macro Pro which is very intuitive and easy to operate for us non/semi-programmers.
