Hi Guys,
I've updated my free PBR Shader Pack to version 2. Usage hasn't changed all that much but a fair amount of tweaks have been made internally, some of them inspired by BlenderGuru's recent 'fixes' to his PBR setup and some of them just from things I've noticed in my day to day usuage of them. The biggest obvious one being you can now manually control the amount of gloss at facing angles for more artistic control.
For full details please see this post.
And below is the original usage video, which has not been updated:
