Write a series of MFX files based on the model's Skeleton.
This function creates an MFX file for each Skeleton Joint and writes all the vertices attached to that Joint to a file named after the same Joint, i.e., ELBOW.MFX. The Joint (x,y,z) position is used as the Model Center for each model in the MFX file. Edges and faces attached to vertices written to a particular MFX file are also written to that MFX file. This command is nearly the same as the File > Export Model > Letters command.
Specify a directory where the data is to be saved. For complex models, it's a good idea to set aside a subdirectory within the MODELS directory for all the pieces, and to keep nothing else in that directory to avoid confusion.
