Which software can be used to edit .cfg (CAL3D) files

[luakt]

WorldViz comes with a number of animated avatar files such as vcc_male.cfg. However, after checking through a dozen of 3D software including 3ds Stduio Max, Blender, MileShape, Paser, Life Form etc, none of them allows import of cfg files.

Is CAL3D only supported by the WorldViz internally and users are not allowed to create own avatars?

Or, do we need to combine cfg and its associated files to a single file?

Also, I do not find any software that can be used to export animated characters in cfg and associated files.

Kindly help!
