Jade Tiger will be a tough one to convert. It has a lot of extra bones. The technique uses Daz Studio's Transfer Utility and the GenX plugin. Essentially, The GenX tool copies the character morph into the clothes and the Transfer Utility to copy character's regions/groups into the clothes. Then, you have to update the base geometry. Make any corrections because the groups are not matching up.

If you are still interested, I'll create a detailed description. But, that will take a while.
