<div dir="auto">Understood that .glTF avatars are still a WIP. Last I heard, work was being done with the VRM [sic] Consortium (?). Perhaps we should try to mix in our form of HAnim JSON in October, after the Web3D Conference. Michalis, can we submit our own Khronos extension designs?</div><div dir="auto"><br></div><div dir="auto">I’m about ready to call this project a wrap for now, subject to revisiting later, based on potential designs. I am open to mapping more joints from other models and bringing forward the v1 models in the archives. Some of my code has dependence on animation for renaming joints and interpolators, so some alternate projects might export what happens when no animation is specified, or work on extending which Interpolators and Sensors to incorporate in mappings. I think the more things we handle, the more valuable X3D and HAnim become.</div><div dir="auto"><br></div><div dir="auto">Great work bringing the HAnim standard forward, Aaron, and making us consider joint and interpolator renaming for transportable avatar animations.
