Lighting ini files and general questions

Hi.

Looking after some good tutorials about how to edit the .ini files for lighting purposes. It’s a whole new concept for me and I can’t find anything really useful.

Also, if you have any thread or tutorial about good practices for photorealism in Unreal I will be thankful.

Sorry for the request, but it’s kind of difficult to search over the tons of basic tutorials and stuff like that.

Thanks.
