Marc Potocnik explains in depth the theory behind reflectance, providing a glimpse of how he uses reflections in Cinema 4D to achieve outstanding renders for Audi.
04:52 Metallic Car Paint - Theory
10:19 R15 Metallic Car Paint (Lumas)
17:48 R16 Reflectance Channel
23:43 Diffuse Models vs Global Illumination
26:35 Masking & Fresnel
27:13 R16 Metallic Car Paint Shader
28:24 Legacy Specular
29:53 Directional Reflection
35:50 Electromagnetic Immunity - Intro
45:14 Circuit Board
Marc first discusses some theoretical concepts to consider when creating metallic car paint materials. Next, he outlines how to apply these principles via the Lumas shader in Release 15.
Then Marc demonstrates how the techniques apply using Reflectance in Release 16. Marc provides an overview of the Reflectance channel, diffuse models and masking & fresnel, followed by his recipe for metallic car paint using R16 Reflectance.
Demonstrating another project for Audi, Marc shows how he set up the lighting and reflections to achieve a realistic render.
