Lighting problem in my game design in Unreal Engine 5

[JustTryToKillMe (JustTryToKillMeツ)]

Hello dear forum members. As a newcomer to using Unreal Engine 5, I encountered a problem. I will upload a video link for you to understand the problem better, but to summarize the problem briefly, I set up a lighting system with the “Emmisive Material” I used in my game. However, when I play the game, as seen in the video, the lights start turning on very late, and when I go a certain distance, the lights turn off by themselves. They only turn on at a certain distance. Sometimes there is even a complete darkness. If anyone knows the solution, I would be very grateful if you could help me. I wish you all good work.

Here is the link to the video I mentioned : https://www.youtube.com/watch?v=Xi0WsQkEFHM

There is a similar post on Reddit, and someone says “This can be solved by checking the emissive light source option in the details tab of the static mesh you are using as the light.”

Does anyone know why emissive materials in Lumen only light the environment to a certain distance and how to increase the distance? : r/unrealengine (reddit.com)

Thank you for everything. Indeed, when I checked the “”Emissive Light Source” option, my problem was solved.
