I converted an UE4 project to UE5 and I can’t enable Lumen. The drop box is grayed out.
How do you enable this?
I remember some Lumen video, where we are toldt that enabling Lumen will change required settings like Generate Mesh Distance fields automatically when migrating a project, but in this article published on 24.05.2022 the way is to manually enable “Generate Mesh Distance fields” first, then switch RHI and then you will be able to enable features like Lumen.
Maybe you can give this a try.
