What is the supply of those Dynamic Lighting artifacts in Unity URP?


I’m going through the identical drawback time and again with Dynamic Lights in Unity and do not know the place subsequent to look. I’m nonetheless studying unity so perhaps I am lacking one thing trivial as a result of it occurs within the Glasses but additionally in Editor Sport Mode. Precisely the identical factor.

The Drawback:

Lighting typically works however as I flip my head round (meta xr app – see under), specifically if i’m considerably near the sunshine, the sunshine is changed by a wierd sq. artifact that appears associated to the rotation of the top(scene) .. some head rotations make the sunshine appropriately render, many others make the sunshine disappear and that unusual sq. seems as an alternative – on the mild place.

This occurs independently of the “Further Lights” settings (pixel depend …), EVEN WITH ONLY ONE LIGHT within the scene (this instance!)
