2015 – Blender Conference talk: Simulating materials with unusual microstructures

While building a larger scene with Blender, I came across several materials that puzzled me for some time. They were not easily simulated with simple shaders, but required careful observation before a visually convincing material could be built.

In my Blender Conference talk, I present these cases and my solutions to the problems:

  • Retroreflectors
  • CRT TVs
  • Security holograms
  • Wooden surfaces with glossy anomalies
  • Lenticular print simulations with working stereoscopic effects!
