[x3d-public] [x3d] X3D working group meeting: charter review for 2024, minutes 1 DEC 2023

Fri Dec 1 11:38:17 PST 2023

I have not seen improvements between Blender’s 3.6 io_scene_x3d addon and
Blender’s 4.0 io_scene_x3d addon, but feel free to double check me, as my
version may be somewhere between the two.

The Web3DConsortium’s version may predate Blender 3.6.

While we still have to update the io_scene_x3dv addon for 4.0, it’s a
better approach to supporting export for multiple X3D encodings.  There
exist some gotchas right now where you have to make skeleton geometry
transparent.

Has anyone been working on X3D import for Blender?  Can we have a design
discussion?
