MIRRORrsquoS EDGE CATALYSTCHALLENGES

bull Creating a Time of Day system

bull Can we even make Mirrorrsquos Edge with dynamic lighting

bull Making beliveable characters for cinematics

bull Creating stylized images with Physically Based rendering

SHADING FUNDAMENTALSPHYSICALLY BASED RENDERING

bull Frostbite transitioned to PRRhttpwwwfrostbitecom201411moving-frostbite-to-pbr

bull Specular Microfacet model with GGX normal distribution functionbull Diffuse Disney Diffuse with energy

renormalization

bull Now industry standardbull Easier to author textures with other

softwares

SHADING FUNDAMENTALSPHYSICALLY BASED RENDERING

bull Base Colorbull sRGB 40 ndash 230

bull Smoothnessbull Artist driven

bull Reflectancebull Controls fresnel curve of reflectionsbull Physically correct values to follow

bull Metal mask

SHADING FUNDAMENTALSPHYSICALLY BASED RENDERING

bull Dynamic Time of Day loves PBRbull Shading for every lighting conditionsbull Accurate reflections of the environment

bull Game camera is a physical camerabull Accurate Exposure values Shutter Speed Aperture ISObull Realistic Depth of Field
