Did you add the camera here?

Why can you not access the camera using this.context.mainCamera ?
probably can lol
by user 103054507105067008
Updated script, most welcome to use it for samples or anything else!
by user 103054507105067008
Nice, thanks
It’s also really easy to use GUI from three/examples/jsm/libs/lil-gui.module.min.js to change values in real time with sliders on top of this for prototyping, using it for client feedback at the moment and they love it!

Version with GUI sliders added

Very important to note that changing the this.context.composer seems to break XR views, I have made an issue for this here:

Hey, thanks very much for sharing this @ROBYER1. It really helped me get started.
Now I have some questions looking at the source.
It seems to me that this.renderer is assigned to but never used. Am I missing something here?
The reason I’m asking is that I’m having a hard time implement ToneMapping from the example.

For tonemapping you can just use the Volume postprocessing in Unity 
Tonemapping + PostExposure are currently implemented
Using URP Volume right?
by user 732122195614105653
Yes
Awesome! Thanks

Is Tonemapping Neutral working okay? About to test
