Shading Models

• Shading Models Overview:

• Unlit

  • Only outputs emissive color
  • Perfect for:

    Special effects (fire) Objects emitting light

  • Can cast light with:

    Lumen Light mass (if emissive for static lighting enabled)

• Default Lit

  • “Most commonly used”
  • Uses:

    Direct/indirect lighting Specularity for reflections

• Subsurface Types

  • Regular Subsurface

    Light bleeds/scatters through material Has subsurface color option Example: Light through finger/ear

  • Subsurface Profile

    “Geared towards high-end skin rendering” More complex options:

    • Surface albedo
    • Mean free path color

• Specialized Models

  • Cloth

    Has fuzz color channel Simulates light interaction with cloth surface

  • Two Sided Foliage

    For leaves/plants Allows light transmission Better than subsurface for “very thin surfaces”

  • Hair

    Creates natural-looking hair Multiple specular highlighting Mixes hair and light color

  • Clear Coat

    For materials with thin translucent film Examples:

    • Car paint
    • Lacquer
    • Soda can metal
