multiple duplicate bake lightmaps

is it normal to see all my lightmaps similar?



I use forward shading and GPU lightmap in VR.
I don’t know if I loose resources.

I have the same problem. I was using version 4.27 and upgraded my project to 5.6. I was surprised to see 80 lightmaps with the same name in World settings. Then I realized that there are as many duplicated lightmaps as there are meshes in a level.

Please help.:smiling_face_with_tear:

downloaded the source code (5.6.1) and found the problem was in world.cpp.

I compiled the project and only replaced UnrealEditor-Engine.dll in the EpicGames\UE_5.6\Engine\Binaries\Win64 path. You can try this too; it solved my problem. You just need to rebuild your map’s lights.

UnrealEditor-Engine.7z (16.3 MB)

By the way, this bug hasn’t been fixed for two years.:smiling_face_with_tear:
