Hi.
I have my prop using child-actor component at my level and using static light.
but after upgrading my game UE 5.3.2 to UE 5.5.1
It keep saying ‘LIGHTING NEEDS TO BE REBUILT’ when I load level.
When I see Lighting StaticMesh Info
All Lightmap assigned child actor’s static mesh is lost.
If I rebuild lightmap error message is gone and I can see lightmap is assigned at Lighting StaticMesh Info.
But If I reload level It lost again.
It was okay at UE 5.3.2
