Mesh created in Modeling Mode not visible to Lumen (5.4)

[SebastianSchenk]

In Unreal Engine 5.4, when I create a mesh, such as a cube, in Modeling Mode, it is not visible in Lumen view modes. Consequently, reflections inside these meshes don’t work properly.

However it works correctly in 5.3.

Unreal Engine 5.3

Unreal Engine 5.4

Any idea?

It got fixed with 5.4.2.

I guess it was this bug:
UE-213896 5.4.2 - Hotfix Candidate - Distance Field Mesh not generated after modeling geometry
