Short description of error
Material missing on X3D export
Exact steps for others to reproduce the error
When i import

https://wdune.ourproject.org/examples/in.x3d

i get

https://wdune.ourproject.org/examples/out.blend

when i export this to X3D i get

https://wdune.ourproject.org/examples/out.x3d

This file do not have a X3D "Material" node, it is shown full white in a X3D viewer
(freewrl. white_dune or view3dscene).
If you manual add a Material node , it is show in a gray color, similar as it is shown in blender.

Can you upload directly here attached files (drag and drop or use cloud icon to upload from OS)? external link will can broke in future, thus this report will be unusable

IMO this is a function request not a bug, Blender 2.79 and 2.80 .x3d export addon not export materials (as designed?), in 2.81 import and export addons i had a error

If i directly export the default box to X3D in blnder 2.79, i t gets a Material node.

#66534 (X3D export in 2.80 does not save texture) is related

Currently the X3D exporter doesn't handle node based materials at all. Since this ticket has already been marked as a known limitation, I'm setting this ticket to confirmed. Additionally, the H3D Extensions (EXPORT_SCENE_OT_x3d.use_h3d) that was apparently used to previously save shaders is broken. The add-on hasn't been properly update for 2.8x and later as it attempts to use functions that are no longer part of the gpu module.

I've tested this with the current master (2.92).
