About baking lights.

Thank you, sir! But what would you suggest in thius case: there are some point lights in my tavern. Is this possible to lighten the load on recources by baking shadows, but in such a way that they will persist for, let's say, player?

In theory, yes, but you will have to use real-time lighting for the player. It's also quite awkward to do. Basically, make sure to mark everything you want to lightmap as static in the inspector, and it should more or less come out for you. I recommend testing it with a smaller scene, and seeing what happens when you try a few things.

But I'd have to disable shadows from light after baking, as axCed said...
