    Baked emission is not reflected. ❌
    And this is bad.

    Lights is reflected. ✅
    But searchlights must have a lot of lights then, this is bad. I need emission, not lights.

    ❔ Why baked emission not reflected?
    ❔ What options I need to setup to not use lights on whole level and only use baked emission?
    ❔ Why I still don't need to move to Unreal Engine 5?

    Have you set up a reflection probe?

    Yes, I have a baked reflection probe. I don't know the right options. It's not work.

    Hey @Kadae .You seem a bit frustrated by this ;)

    The "reflection" you're seeing from the light is actually a specular highlight and is technically quite different from reflecting an emissive surface. The specular highlights work in real time where any reflection of the environment will need to be baked in to reflection probes. In order to get the effect you want, you will need to use Box Projection. Otherwise it will seem like the reflected environment is infinitely far away. Read more on box projection here and read how to enable them in URP here. From your shared image, I can see you already have it enabled on actual reflection probe, so maybe you only need to enable it on the pipeline asset?
    When using box projection it's important to align the reflection probe to the reflective surfaces of the room (as best as possible). Something like this should work for your setup:

    Thank you for the reply.
    My box projection was enabled like here, but still not work. I switched to HDRP anyway, before the URP killed me. Now fighting with other problems in HDRP. Classic.
