How to work with multiple lighting scenarios?

Hello, I am creating a level where I need to create several options for lighting corridors (gradually reducing the amount of illuminated space).

When trying to create several lighting scenarios, only one bakes normally, all the others have lighting defects.

Are there any guides on this topic, or examples of levels uploaded in the public domain?

Hey there @PEV322! Just to verify, you’re using Precomp Lighting Scenarios right? Since one can be active at a time, if you bake another while one of the other’s is active it can cause heavy artifacting and some users run into this from time to time. Alternatively if the bakes are failing while being prepared separately, I have more questions!

May I know your specs/ Engine version?

What RHI are you using?

May I see the artifacting?

Hi, thank you for your answer.

Yes, I use “Precomp Lighting Scenarios”.

My engine version is 4.27.2

If I understand what you mean correctly, here it is:

And two light scenarios that I rendered:


Thank you in advance
