<div dir="auto">I do think it will be difficult to find the HAnimHumanoid in the EMPTY hierarchy without armature on export. HAnimJoints, etc. are probably easier, if we have a pattern for the DEF prefix, or replace the prefix with “hanim_” on import, or just wing some kind of pattern; more complex solutions, like comparing Joint DEF prefixes might be possible. Having the user type in the HAnim DEF prefix may sound easy, but what about multiple humanoids in the scene?</div><div dir="auto"><br></div><div dir="auto">You’ve heard the arguments for and against armatures, but what do people using Blender want? Armatures or no armatures? Full bone structure, or no bone structure? Bone structure without empties, or bone structure with empties (if possible)? I definitely need your samples, or I will create my own, which may not follow your use case.

<p style="margin:0.1rem 0;line-height:1.0">There should be a way to import the last transform hierarchy example you showed.</p>

<p style="margin:0.1rem 0px;line-height:1">So, I would like to see import/export of last jin-like no geometry loa4 example skeleton I sent, but a main item to advance x3d hanim and blender would be to get the ASCII exports of gltf and related working. For the .blend or from the internal stores the basic stuff for hierarchy, geometry, and animation are in there just needing to be extracted. The gltf and related are supposed to help us get these data types. </p>
<p style="margin:0.1rem 0px;line-height:1">Otherwise, the main item would be to either import or type in a testable loa4 hierarchy skeleton, then figure out how to export it back to x3d. It would be ok to settle for gltf instead of pure x3d syntax. </p>

<div dir="auto">First off, I asked for priorities to work on. Blender was one of the top priorities. So I’m working on it. If you are not interested, I will stop sending to you messages.
