Float bindable
default: 0.0

introduce hue variation in flake color centered at the base flake color's hue on the hue wheel

glitter_color_saturation_variation

Float bindable
default: 0.0

introduce saturation variation in flake color centered at the base flake color's saturation

glitter_color_value_variation

Float bindable
default: 0.0

introduce value variation in flake color centered at the base flake color's value

glitter_compensate_reference_space_deformation

Bool
default: True

(In ReferenceSpace) Compensates for stretch/compression/shear in glitter shapes resulting from animation etc

glitter_debug_mode

Int enum
  0 = “off” (default)
  1 = “blend”
  2 = “color”
  3 = “averageColor”
  4 = “footprintArea”
  5 = “radius”

developer debug visualization modes

glitter_density

Float bindable
default: 1.0

controls the number of flakes per unit length; larger density packs more flakes into same space

glitter_jitter

Float bindable
default: 1.0

Controls how much the flakes are randomly offset from a regular grid

glitter_layering_mode

Int enum
  0 = “physical” (default)
  1 = “additive”

layering mode for glitter on top of the under material. physical: conserves energy and glitter attenuates under material, additive: breaks energy conservation but glitter is never darker than the under material (eg. use case: snow)

glitter_randomness

Float
default: 0.5

randomness of flake orientation

glitter_roughness_A

Float
default: 0.14

specular roughness of individual flakes (0 makes flakes mirror-like)

glitter_roughness_B

Float
default: 0.14
