Realistic outdoor rendering (VRay like)

Hi, I have an outdoor scene and I’d like to render it in a very realistic way, can someone give me suggestions or links to examples or tutorials?
So far I’ve found something for interior render but nothing specific for outdoor.
I need to know especially how to properly set daylight (directional light, atmospheric fog, skylight, global illumination, AO…)
Thank you so much,

I am looking for same thing. I can’t do some thing like vray in ue ye
