  • indexOfRefraction: Float
  • ambientColor: Color3
  • reflection: output of the Reflection block
  • clearcoat: output of the ClearCoat block
  • iridescence: output of the Iridescence block
  • sheen: output of the Sheen block
  • subsurface: output of the SubSurface block
  • anisotropy: output of the Anisotropy block
• Outputs:
  • ambientClr: Color3
  • diffuseDir: Color3
  • specularDir: Color3
  • clearcoatDir: Color3
  • sheenDir: Color3
  • diffuseInd: Color3
  • specularInd: Color3
  • clearcoatInd: Color3
  • sheenInd: Color3
  • refraction: Color3
  • lighting: Color3
  • shadow: Float
  • alpha: Float

Notes:

• The Dir suffix in the name of the outputs means Direct and are components from direct lighting (spot, point light, directional, ...).
• The Ind suffix in the name of the outputs means Indirect and are components from indirect lighting (IBL, ...).
• The lighting output is the combination (sum) of all the other outputs (except for shadow and alpha) and is the one to use if you want to deal with the final output color. This color is in gamma space.
• All the XXXClr, XXXDir and XXXInd outputs are individual lighting components and can be used if you need to perform further processing with them. These components are in linear space.
• The shadow output is the shadow component when this material is used for shadow rendering (0 means completely in shadow from all lights and 1 means fully visible by all lights). You can use it for additional special effects (see Tinted Shadows Example ) for tinted shadows for eg - it's for the standard material but it would work the same for PBR too) but note that you don't need to do anything with it by default to have shadows rendered correctly for your material
