PBR Organic ShaderLib
Hi! I just made a PBR shader library add-on for Blender 3D that contain translucent, refraction and SSS material. It's still a prototype and it's free to use. If you find the default shader in this add-on is familiar, you probably have already watch Andrew Price (Blender Guru) tutorial on 'How to Make Photorealistic PBR Materials' part 1 & 2.
The python that I used had similar code with PBR add-on by Wolf & Nathan Craddock (I'm not a programmer). So, I would be glad if someone will fix this add-on python code. If you mind, please give comment and review to this add-on so i can develop it better.
Download PBR Organic Shader Lib in here (Google Drive).
Download and install the zip folder into Blender. Will work only in Blender 2.76 and above.
