It’s all about setting up your landscape material :
https://docs.unrealengine/latest/INT/Engine/Landscape/Materials/index.html
You’ll want a layer for grass and another one for rock.
When you need a video tutorial just go to youtube and type in “landscape material” 
I tried but the ones I found we’re really fast.
e.g ?v=tsXVP0fykBM This one here is just about landscape painting. When you have any special questions about what he is doing or what you dont understand, just post them in here
