Support KHR_lights_punctual

[revyTH]

When exporting a scene that contains lights, for example PointLight and then import back in three.js I found that the lights are imported as generic Object3D, instead of light type. Is this the expected behavior?

This is deliberate, as glTF does not have a native concept of lights. There is a ratified extension for them, and I expect at some point UnityGLTF will support that, but progress is slow.

Ah ok, thanks for the information

Updating the title of this to track support for this extension

Hello, can you please confirm this is the active thread concerning including scene lighting in Unity GLB exports and if there is any update on status (or, if I should be looking elsewhere?). thank you!

On a related note: I have noticed the WaterBottle.glb example has nice lighting that looks to be scene driven. But, I cannot figure out how that was achieved. Does anyone have an idea how that lighting was accomplished?

Thank you.
