Sorry, you’re giving me conflicting information here.
If you really want to bake, then yes, static, Lumen off etc.
But you only really need to do that if your target platform is low end mobile phones.
It’s a trade-off anyway. Yes, you have less lighting overhead for your level. But if its bigger than a few rooms, you have a large memory overhead to store all the lightmaps. So, its not a total solution.
