<div dir="auto">Thanks, Don, for the reference to Holger’s work. As of a month ago, the export of “Future Bike” is still not exporting well from Blender because there are 2 hierarchies, one for transforms+meshes, and one for bones(joints)+meshes. Parenting a mesh to a bone apparently works on export, but animations also are laggard. Eventually, we will want to parent HAnimSegments and HAnimSites that are not quite in Blender yet to bones(joints).</div><div dir="auto"><br></div><div dir="auto">I will continue with this problem until I give up, if anyone wants to lend a hand.</div><div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Thu, Jan 15, 2026 at 5:57 PM Don Brutzman via X3D-Ecosystem <<a href="mailto:x3d-ecosystem@web3d.org">x3d-ecosystem@web3d.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><div>Yes, thanks for minutes, super helpful.

The "Castle Skin node" is an extension for that player. A number of us looked carefully at that in a meeting. There are some issues (e.g. overloading HAnimHumanoid skin field with a new node name) and relevant opportunities for further development to match the emerging examples for Coveroid design (i.e. clothing and apparel matching a Humanoid). It will not be added as a draft node to the spec without further improvements, such as naming and more general purpose and not adding "node bloat" if there is no gap to be fixed.</div><div><ul><li>[hanim] Michalis Kamburelis to describe glTF conversion to X3D as experimental Skin node; Friday 12 DEC 2025, 09-1000 pacific</li><li><a href="https://web3d.org/mailman/private/h-anim_web3d.org/2025-December/002563.html" target="_blank">https://web3d.org/mailman/private/h-anim_web3d.org/2025-December/002563.html</a></li><li>I thought we recorded it on YouTube but am not finding link...</li></ul></div><div>b.
