PBR Baker

Simple open source multi-functional baking tool for PBR material ralted work, inspired by various techniques from the SIGGRAPH 2018 presentation "Material Advances in Call of Duty: WWII" by Danny Chan.

Written in mostly portable C++. Uses glm and stb libraries.

Features

• Environment BRDF lookup table - Karis'13
• Simple noise texture generation ( only white noise for now )
• Black body radiation table
• GGX gloss to average normal length table bake - Chan'18
• GGX gloss combine lookup texture bake - Chan'18
• Pre-integrated Skin Scattering - Penner et. al
• Gaussian / smoothstep wrapped lighting tables
