I am new to Unreal and i am trying to make an fps open world low poly game. How should i do it? Any good tutorial out there about open wold lowpoly level design? Thiswould be what i am aiming to get.
You basically answered your own question with the link you gave. The low poly effect is done by that material setup.
The landscape itself is done using UE4’s built in landscape tools.
There are tons of tutorials about landscapes. Simple search for “unreal landscape” on YouTube found, for example: https://www.youtube.com/watch?v=sTAVY8qtGbg
