I’m assuming that “production lighting” is build > lighting quality > production?
I just gave that a try, and rebuilt lighting (and pretty much everything else, for good measure), and the problem still persists. As you can see in my previous screenshots, the nanite LOD issue seems to only affect certain meshes in the scene - one mesh will have very high quality mesh and texture, but the mesh right next to it will have terrible quality texture and very low poly. It doesn’t seem to be an issue with the mesh itself since other people have mentioned that dropping in another instance of the same mesh may not have the same issue.
I don’t see how it could be a lighting issue, since its affecting both texture and geometry, but nanite+lumen is pretty sophisticated so as a beginner there is lots I don’t see lol.
do you have any other suggestions that could remind UE that these are nanite meshes and not just low-quality static meshes?
