This is the reference image that’s why. THAT IS Gilneas…
@ OP, Use a directional light and a sky light, set the sky lite to have very little power, as well as the directional light.
Adjust the light colour of the directional light.
Use an exponential height fog. Alter the colour of the fog to somewhat match the scene here. Also increase its density, start distance and so on.
Which do you want? :You can’t do hand drawn and realistic XD
Hand drawn stuff is exactly that, you either hand draw it and scan it in, alter it in Photoshop, or hand draw it entirely in photoshop.
For more realistic stuff you could use cgtextures.com for source images, manipulate them however you want.
The art style can take a while to get how you want, it takes time and effort. That being said, I do’t see anything overly complicated in any scenes ive seen of this place (Don’t play Wow btw)
Landscape, low poly static meshes, simple materials, lots of fog, really cloudy sky dome.
