Problem with making mountains

Hi,
I am trying to make some mountains, i am new to unreal engine so i done the tutorials and after spending a lot of time i cant seem to mould the mountain or get the texture right. I then saw the textures on the landscape mountains but cant seem to get the texture to look the same. Anyone know of a video of someone making a snowy mountain (already googled and there isnt much in the way of tutorials for snowy mountains that i personally could see) that i can use as a tutorial or any advice since i am lost on how to make something look nice.

to get realistic landscape you should use some terrain generator and import height map and other textures from it.

try to google tutorials for World Machine 2.
