Guidelines on lighting

What are some good guidelines for creating good lighting in an outdoor scene? I know that this may depend a lot on the time of day and setting, but in general when working in UE4 what are some good guidelines? Also, considering the material workflow as well. I think some of it has to do with your PBR material workflow correct? Tweaking material settings to get the right look and reflection or roughness, whichever look you’re going for. Anyway, any advice you guys can offer would be nice. Thank you.
