Daz has started a rebranding process beginning from logo. All hints to a repositioning of the firm in the semi-professional market, distancing in the process from any connection with Poser. They do not want to "crush Poser users" they want to make people forget about their Poser related roots <sarcastic icon, unsupported by those shitty Emoji).

Morph3D offer is not a half-baked external tool but an integrated, hosted within Unity3D, game character customization environment, something not even comparable with Poser (and, AFAIK, free).

The OP was asking about G3, there is no DSON support for G3 in Poser. Considering that SmithMicro has selected a render engine different from Iray, I don't see why they should add the critical dual quaternion skinning to Poser. You know the drill, cutting the nose to spite the face.
