color – defines the base albedo color of the material; it’s the starting tone under all lighting and reflections.
roughness – controls surface smoothness; 0 means a perfectly smooth, mirror-like surface, while higher values make it more matte and diffuse.
metalness – determines how metallic the surface appears; values near 1 simulate metal, affecting how color and reflectivity behave.
emissive – adds self-illumination color independent of lighting.
dispersion – splits transmitted light into rainbow edges; higher values exaggerate chromatic fringing.
thinFilmIOR – index of refraction for thin-film interference, driving color shifts.
thinFilmThickness – film thickness in nm; larger numbers widen interference bands.
clearcoat – strength of the transparent lacquer layer.
clearcoatRoughness – haziness of that lacquer (0 glass-smooth, 1 frosted).
reflectivity – scales environment reflections without changing metalness.
transmission – controls optical transparency (glass / liquid effect).
thickness – physical depth in meters for refraction and subsurface tint.
ior – base index of refraction; 1.0 ≈ air, 1.5 ≈ glass.
attenuationColor – tint applied to light as it travels through the volume.
attenuationDistance – meters before the tint reaches full strength.
iridescence – enables thin-film color shift separate from clearcoat.
iridescenceIOR – refractive index of the iridescent layer.
iridescenceThicknessMin – minimum film thickness in nm.
iridescenceThicknessMax – maximum film thickness in nm.
sheen – strength of the soft fabric-like edge highlight.
sheenColor – color tint of that highlight.
sheenRoughness – blurriness of the sheen glint.
specular – overall specular intensity for dielectrics.
specularColor – tint of specular highlights.
Flat Shading – toggles faceted rendering instead of smooth normals.
