I go through the entire process of using these textures, starting with combining the separate levels of detail into a usable rgb map. I do this in both Photoshop and nuke. I then launch into Mari where I give a quick into to the software and then we begin with projecting on the diffuse maps and then the displacement maps.

I also provide a couple of side tutorials which go through my process of creating tile-able textures in photoshop as well as my process of taking the finished displacement maps back into zbrush where we can continue adding details and irregularities.

This is a step by step tutorial separated out into 20 chapters. I don't skip any parts of the process and I don't use time lapses at any point.

 
The software used in this tutorial is:
Mari
Zbrush
