The choice of mesh and clothes is made in the file proxy.cfg, located in the same directory as the MH program. The instructions in the file are hopefully sufficient.

I have tested to import the dae files into Blender 2.55 without problems. It does not work with Blend 2.49b due to some encoding problem, but this should not be a big deal since you can save a blend file in 2.55 and open it in 2.49b. The dae files have not been tested with other software, and I would like to know if there are any problems. In particular, there is an extra, small bone at the end of each chain. This was necessary to make things look good in Blender, but may cause problems elsewhere.
