Creating high quality film (not for use in game)

Hi Everyone,
I am an enthusiast of animation! I want to use Unreal to produce high quality animation from Unreal and don’t need to limit any render settings as I won’t be creating a game. Can anyone recommend any tutorials or settings to produce the highest quality looking frames (preferably without baking of GI) just using dome lights and ambient occlusion. Thank you kindly for any assistance anyone can offer.
