in UE5.4.2, when having Lumen Disabled, random objects in my world are basically glowing, or Unlit. Some objects with the same material wont glow, yet some in another area do. I do not have any lights causing this, and the problem goes away when Lumen is enabled. It is also not only static meshes, but happens with foliage too. Anybody know how to fix this?
It might be the skylight, you can also try flipping through the different visualization and optimization view modes to try to narrow down where it’s coming from.
In Unreal Engine 5.4.2, if you’re encountering issues where objects appear glowing or unlit when Lumen is disabled, consider checking a few key areas for resolution. First, verify that your static meshes and foliage have appropriate lightmap resolutions, as low resolutions can cause lighting inconsistencies. Ensure that material settings for affected objects are correctly configured, particularly focusing on emissive properties and shading models. Additionally, ensure you have built lighting for your scene to leverage precomputed lighting data effectively. Review post-processing effects and their impact on object appearance, and consider adjusting Unreal Engine console variables related to lighting and rendering. Lastly, check for updates or patches that might address rendering issues in your version of Unreal Engine. These steps should help troubleshoot and potentially resolve the issue of objects appearing incorrectly lit when Lumen is disabled.
@jeffrey597doss That is chatGPT nonsense and is not at all helpful to anyone.

Alright, I have tried messing with the skylight and looking through different viewmodes and I still cannot find anything. However, I copy and pasted my map to avoid breaking anything, and after loading into it, there were no problems with the glowing objects, everything was correctly lit? I made no adjustments to anything before loading the map or even after, yet everything was fixed. I still cannot get it to be fixed in my main map though.
Update: I have figured out the issue. It was caused by previous baked lighting (Dont know how, since I haven’t baked in this project). But by going into world settings and checking the ‘Force No Precomputed Lighting’, then building, everything worked as intended.
