<div dir="auto">For clarification, should I download the LOA4 VRML example in HAnim pt1 Annex A? I’m wondering how to read VRML into X3DJSAIL or x3d.py?

It's a real simple <br>
script that loads the .x3d file, then prints out all the DEFs it <br>
discovers in the scenegraph. More development later as we narrow down <br>
what we want to do.<br>
<br>
<br>
Looks like there may be an issue with the containerField in the <br>
humanoid_root of the .x3d file mentioned in the Subject?<br>
<br>
<br>
Please advise. I tried "children", but got a second set of errors <br>
below. I tried "joints," similar issues.<br>
<br>
<br>
There are around 38 DEFs in the model, which seems a bit low. I grabbed <br>
the model with HAnimMotion.<br>
