I worked on it at the begining of the year to play around with the new PBR pipeline in 3D Coat 4.5.It is an amazing tool, we can do really amazing stuffs really fast. I had to tweak some things to be compatible to Sketchfab, but it was really fast and fun.I only used Maya, 3D coat and tweaked stuffs on Photoshop for this shaderYou guys can download and play with it if you want, it is a good practice for creating PBR materials.
