Lighting issues

Hello everyone, I have some issues with my ligting, I have hiden statics mesh with emissive (a LED strip), but when the mesh isn’t visible, i don’t even have indirect lighting and i don’t know why, anybody can help me ?

i’m currently on UE 4.27.

That’s weird, if the light is baked it shouldn’t go away even if you delete the geometry.

It looks (by the point light icon) that you are actually working on UE5 and not 4.27

In UE5 I’ve experimented the same issue, it happen because your light is too thin, Epic advice is to to use big dim light sources to work with emissive in Lumen.

In my opinion you’ll get better results with a light, it is widely known in 3d that lighting with emissive usually ends up in poor quality or bad behavior
