Why is Lumen worse than Screen Space with UE5.1?

Why is Lumen worse than Screen Space with UE5.1? Since version 5.1, I have big problems with the light, you can only see what is lit, as if the indirect lights do not work?

Does anyone know why Lumen gives me this rendering? The shadow is too dark on the astronaut


It looks like in the first one you’re just getting no indirect lighting at all, which normally points to a configuration error that’s preventing lumen from working at all.

First, make sure you’re on shader model 6, directx12 (or vulkan).

Make sure lumen is enabled under global illumination and reflections.

If it’s still not appearing, then it could be a bug.
