OK, just see that without being able to deal with the idea of a Joint transform 'center' then how does skeleton animation work? <br>
Also please notice that center is expected animation parameter in any x3d Transform.  <br>

<br>
I wasn't talking about armature/bones (skeleton/joints) export or<br>
H-Anim when I mentioned above. And I really don't want to go into a<br>
discussion about Blender armature system in this thread -- we're<br>
off-topic here already (this thread was intended about texture<br>
transforms) :) I already said what I intended in other thread --<br>
Blender is fully capable animation system used by artists for years in<br>
countless animations. I'm sure it can support whatever you need.<br>
<br>
In above cited phrase, I meant that a *first* step towards supporting<br>
animation export (in Blender -> X3D exporter) should be IMHO<br>
supporting animating Blender object's location/rotation/scale (without<br>
Armature/Bones, just set keyframes on these things in Blender).<br>
Because<br>
<br>
- This is what I would consider (and I think artists would agree) the<br>
most trivial possible animation method. No bones/joints, no<br>
skeleton/armature, some objects can just move/rotate/scale around.<br>
It's trivial, and it allows to express some things (like stuff flying<br>
around the world).<br>
<br>
- This trivial animation method is also simple to express in formats<br>
like X3D, glTF. Again, no need to deal with skin/joints.<br>
<br>
- And it is simplest for Python / X3D developers to support. No need<br>
to deal with skin, weights, joints. Start simple.<br>
<br>
Supporting animation using armature/bones (skeleton/joints) export /<br>
H-Anim is the next step. Let's first prove we can handle the basics.<br>
<br>

><br>
><br>
><br>
