How to Setup a PBR Material for Cycles Render in Blender

Cycles is Blenders PBR based production renderer. 

Cycles is capable of using GPU based rendering, more information on that can be found here:
https://docs.blender.org/manual/en/dev/render/cycles/gpu_rendering.html

Getting Started:

Press Shift+A to bring up the add menu then navigate to shader>Principle BSDF.

Importing Bitmaps

Bitmap images for the material can be dragged into the graph editor.

Roughness:

The roughness map will need to be inverted.

Normal:

Ensure the normal direction is correct when plugging it in at this point. 

Setting the Color Data:

Everything needs to be set to non-color data except for albedo.
