programmatically read extras / custom properties from remote GLTF in Godot 4 gdscript
# For more sophisticated use of loading remote GLTF (with extras) use the xrfragment.org spec & xrfragment.gd script
# XRFRAGMENT.ORG is a mini-spec which standardizes 3D metadata without fileformat or platform lock-in
#
# Usage:
#
# load("https://xrfragment.org/index.glb")
# var doc = GLTFDocument.new()
# var state = GLTFState.new()
# #state.set_handle_binary_image(GLTFState.HANDLE_BINARY_EMBED_AS_BASISU) # Fixed in new Godot version (4.3 as I see) https://github.com/godotengine/godot/blob/17e7f85c06366b427e5068c5b3e2940e27ff5f1d/scene/resources/portable_compressed_texture.cpp#L116
# var error = doc.append_from_buffer(body, "", state)

Open Cubic Player Nix-file attempt (newbie needs help, this nix-file is stuck on libancient)

Due to lack of nix-skills I gave up on compiling it via nix (and ideally submitting it upstream). For now, I'm just using the AWESOME ocp player via this ~/bin/ocp shellscript:

#!/bin/bash
nix_windows(){
  test -d ~/apps/ocp || {
    mkdir ~/apps/ocp
 cd ~/apps/ocp
