Hi povmaniaco,
Sorry, I did not notice the other thread. All renderers crashed the pure python version, and when figuring out what went wrong I modified the files to handle clothes. Hope you don't mind about that. To set up clothes and hair, the same code is used as by the collada and clothed obj exporters, which is a great advantage.
I managed to make a povray render of the same scene. Again there are no clothes materials, and the character mirrored.
