Some documentation on how light estimation works please.

Please add some documentation on how light estimation is supposed to work.

Here is the documentation: https://docs.unity3d.com/Packages/com.unity.xr.arfoundation@2.2/manual/index.html

Thats great, but does it actually change the scene lighting. I tried to take a look in "ARLightEstimationData" in Visual Studio, but it is nowhere to be found.

Users can't test this easily since the AR Foundation remote is broken. Why not just take a minute to explain how it works? Do I have to set scene light data manually or is it simply done by magictm?

 

You need a script to retrieve the light intensity from the camera frame and apply it yourself on the Light component. See the LightEstimation.cs script in arfoundation-samples.
