Since Khronos has formally submitted glTF as Publicly Available Specification (PAS) to ISO, we should be able to confirm that we are fully aligned.  Michalis please meet with Dick and Don to sort out Mantis status.

My status of EnvironmentLight thoughts is in
https://github.com/michaliskambi/x3d-tests/wiki/Image-Based-Lighting-(EnvironmentLight-node)
. Initial CGE implementation is done, but it needs finishing and
testing in more real-life cases. So, it's not finished, but advanced.

The EnvironmentLight question should really be separated from the
"glTF and PBR" stuff :) glTF spec doesn't even have lights at all, and
EnvironmentLight (aka "image-based lighting") makes sense for both PBR
and non-PBR materials.

Please propose a meeting time next week (and put it in the calendar
invite, to avoid any timezone confusion :) ). I'll happily meet and
talk.

We do plan to support VR in Castle Game Engine (and view3dscene). As
it happens, I have just received Oculus Quest last weekend, thanks to
Rick Lentz: https://castle-engine.io/wp/2022/01/16/oculus-quest-2-developer-mode-for-castle-game-engine-enabled/
. I am excited about porting CGE/view3dscene to VR, using it as my
test device :)

Note:

- view3dscene is not a web application. WebXR is not for us. At least
for now -- we do plan a port of CGE/view3dscene to the web in 2022
(using WebAssembly in FPC, see
https://castle-engine.io/wp/2022/01/01/summary-of-2021-plans-for-2022/
). Then indeed view3dscene could use WebXR (on the web) for VR.

- Our first API for VR will most likely be using OpenXR. So, quite
similar to WebXR, just on desktops/mobile.
