Hey, I have recently ran into an issue with static lighting inside blueprints as components. In UE4.27 everything worked fine when baking lights, now in UE5.1 it only bakes the lights which are placed as their own separate thing. I am not using Lumen and have forward rendering enabled. Dynamic lights work as expected, but I have little performance headroom. Thanks in advance.
I just ran into a similar situation. When I try to run a classic lightmass-build the static meshes placed manual inside my blueprints disappear and appearently also the lights inside the blueprint (bad when you use a sky blueprint). BUT all static meshes that are added via nodes (“add static mesh component” for example) are still there.
Maybe you can do a workaround by adding your lights via nodes. I just tried that and light components added via nodes get baked. Otherwise the GPU Lightmass MAY work for you but I have troubles with that too. Nonetheless this needs to be fixed.
edit:
I just found this here:
There is mentioned that when deleting all BSPs (The funny geometry bush actors) from your level and then run “build lighting only” the lightbuild works fine. This actually seems to solve the problem with the disappearing bp-components while classic lightmass.

Thanks, I’ll try that out and see if it works.
