Looking for Tutorial

Hi, I am interested in a tutorial series that I can seem to find with Digital Tutors or any other website.

In EvilmrFranks video here

[video]Creating a quick Unreal Engine 4 desert scene - YouTube

He is sculpting a terrain where when its sculpted it has a rock texture on the sides and sand on the top? How is this made? I realise this looks like the material from the free demo they had a while ago, but is there a tutorial for it somewhere in the mighty web?

Mr. Evilmrfrank, do you have a tutorial?

Thanks

Have a look down this
