Hello!
I have problems with the light of my map.
It’s an underground level with no external light.
I only use spotlight and emission material.

My lights change when i move my character, seems darker in the side.

Blue circle is the opposite

Seems like the wall reflect on the floor.

Thank you for the help

That’s one of the limitations of Lumen in some light setups like yours.
It uses screen space with raytracing as Screen-Tracing to generate the lights and shadow bounces.

As you move your character/camera sometimes you will see pop ins for both light and shadow.
If you need very fine tuned approach maybe bake those lights? Or go full ray tracing

try changing to detail tracing.
