Zsphere /Mannequins should output FBX bones. Same ones that it uses to build Zspheres and Mannequins should be output as bone chains for Maya rigging. Huge time saver no matter how the model is sculpted. Should be especially so with Mannequins and custom Mannequins.
This feature is immediately apparent many years by Artist, who are Zbrushers and animators/riggers. It would save a lot of time building rig in Maya especially if we had the Sphere or Mannequin centeroids or bone converted to bone chains. We can reorient the skeleton axis ourselves if need be and throw and HIK rig on it (names not necessary). This would work for spider rigs as well as other creatures. I can already see a skeleton bone chain when making Zpheres/Mannequins, why not export them via FBX plugin option?
