Build lighting after game start

I have a random level generation. And i need to build lighting after game is started, and level is spawned.
Is it possible? Because using movement lighting everywhere is very hard for PC. And is it possible to use reflection capture in the similar way? Or may be possible to generate level before game start?

Hey Ignisor,

Light building needs to happen within the editor since it requires an extended time and an external application to successfully build. Your next option would be to make your scene entirely dynamic so you do not have to worry about building your lighting.

With the recent implementation of Distance Field lighting, dynamic lighting is actually very performant depending on the size and scale of your procedurally generated game. Reflection captures cannot be updated at runtime as it deals with light building information.

Take a look at the documentation we have on Distance Field Lighting to get a better understanding of how to set it up as well as use it in an effecient manner.

Let me know if you have any other questions.
