Creating the landscape - sculpting planes in the Landscape Mode. I decided to use 3 layers of landscape to create the illusion of space.
Texturing the landscape - I used a tutorial (https://www.youtube.com/watch?v=zY8AtjM2Jxg) to create a variation on the grass texture and created two instances of it - closer and further.
Using the HDRi texture applied to a sphere to create sky for the level. The texture presented before applying colour correction and after.
Weather system - using the ExponentialHeightFog component to create dense fog.
