As I'm sure you recall, EnvironmentLight was definitely something we tried to accomplish earlier as part of X3D 4.0 finalization. It was not quite finished then, but certainly remains of interest as we all continue working to maintain interoperable loading

Thank you enormously for everything you're doing to keep this<br>
coordinated. Onward we go!<br>
<br>
From my side, things I'd like to design as X3D extensions and propose<br>
to be included in the next version of X3D standard, hopefully some time in 2025:<br>
<br>
- An (optional of course) way to specify mesh data as binary blobs, in<br>
a way compatible with glTF:<br>

The pages above contain information about the details - why I think<br>
it's useful+important, what I know, what I don't know and need to<br>
learn (including experimenting with implementation) to make it happen.<br>

Let's have a productive 2025 :)<br>
