Ernyoka1, No, Poser doesn't run in Linux. But my script does. It's easier to make sure that it works in OSX if I also test it in Linux. Little Dragon, No, it doesn't convert mc6 files yet... but it's pretty easy to write a script for that. Just paste this line in a new *.py file (i.e. 'convert_mc6.py'): self.node.get_child('mtlCollection').rename('figure') Then open a mc6 file in pyMPE and use File->Run Script to run your new script. Then press the "Convert to P4" button if you want a P4 MAT file, and finally save the file. I tried to make extending the featureset of pyMPE as easy as possible. You can do a lot with just a few lines of code.
