Hi , when I investigated your scenes before this was due to the meshes not being modular enough for Lumen’s Surface Cache to unwrap. Check the Lumen Surface Cache viewmode, if it’s all pink then that’s your problem. From the doc:
Only meshes with simple interiors can be supported — walls, floors, and ceilings should all be separate meshes. Importing an entire room, which includes furniture, in a single mesh is not expected to work with Lumen.
Even if that particular case worked better in Early Access, we’re moving forward with what we have now, which works much better on scenes that were built to Lumen’s content requirements (modularly built).
