Hi @Jimbohalo10 ,
Thanks for trying. Did you test it considering it’s a fully dynamic-lighting sample project? Lumen and ray tracing are enabled, but you should see lighting, of course (just dynamic).
Probably, the “RayTracing_edges_artifacts_source_radius.umap” was able to build the lighting because I accidentally placed a Stationary Spot Light, instead of Movable. Anyway, all the scenes should work fine with Lumen, showing dynamic lighting. Maybe you have encountered a new related bug
