UE5 for M1 Apple Silicon

[MickL]

I built UE 5.1 (as described above) but Global Illumination is not working at all for movable objects (neither with Lumen and Standalone Ray Traced). Further setting a light to static in Lumen results in no light at all and no GI.

Hey guys and @RichmarIII could you please explain how you made Lumen working or did it just work perfectly out of the box?

Anyone else having this problems with UE 5.1? And was it working before with 5.0.x?
