Gumroad - Mari Nodegraph PBR Texturing + Look Development

Title: Gumroad - Mari Nodegraph PBR Texturing + Look Development
Info:
In this tutorial I will go over PBR texturing in Mari 4 using ONLY the nodegraph. The idea behind this workflow is to recreate the workflow of substance inside of Mari. I use the newest extension pack in this tutorial to utilize "radio nodes" however if you do not have access to the extension pack you can still get along just fine with the standard Mari nodes.
Once the texturing is complete we will take our textures into Maya and go over the look development process where we create a production ready master shader by using custom RGB masks to blend everything together. For this section we will be using Arnold 5.
