It is an building with furniture
Unreal Engine 5.2
We used the collabviewer template
Building has windows, there is no lightning in the building.

This is how it looks with lumen turned on

For performance in VR I want to turn lumen off Settings:

Result for chairs in the building. Strange “shadows” appear. Even when I turn shadows off for the chairs. Nanite on or off for the chairs does not change anything.

If I put the chair outside the building. No problem

If I put a light inside the building, it looks better

If I turn cast shadows off in sky_light
Settings:

Result. FPS goes up! Ofcourse it is not like with lumen on.
