I'd like to package it but I do not know yet how.

How do cloth merchants do that with the bones and spheres, is there any template of DAZ that may be redistributed? As cloth must follow the rig of the original figure I assume it uses the same rig (with slight adjustions).

I want to try to make sort of a "dummy" cloth without geometry that stores the multi bone setup for the entire figure (reusing the original rig for the unmodified parts). Then one could use Figure->CopyJointParams  to take over the new rig to an existing V4, which just needs the additional bones, but I think that is manageable somehow, either with Python or some other hack.

What is the way cloth merchants do to take over the DAZ bones into their figures without copyright violation?
