<p class="MsoNormal">The “humanoid_root” joints are there. However, the bone wireframes displayed in Maya are based on the rotation pivot (aka HAnimJoint ‘center’ field).<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I’m guessing that you might be expecting bone wireframe to start it’s render at the grid origin? IDK… we can discuss it at the next HAnim group meeting to determine if I have it wrong.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Could they be exported as glTF? Probably, but it’ll be a while before I get around to exporting to that format.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">10-ish years ago, I tried to write an X3D/glTF exporter (that I called BaconXjF) completely in MEL to support export from Maya LT.<u></u><u></u></p>

<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">Back then though, I didn’t’ have the freedom at work to develop an exporter the way I do now.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I don’t really remember anything at all about how the glTF format works. But I suppose it would be easier in Python.<u></u><u></u></p>
<p class="MsoNormal"><u></u> <u></u></p>
<p class="MsoNormal">I’m willing to collaborate with another programmer to implement a glTF exporter for RawKee. Or collaborate on a funding proposal to hire a programmer.<u></u><u></u></p>
