Fields

base_color: Vec4

RGBA base colour (alpha = opacity for glass/transparent surfaces).

metallic: f32

0 = dielectric, 1 = metal.

roughness: f32

Perceptual roughness [0, 1].

fresnel_f0: f32

Schlick F0 reflectance at normal incidence.

sss_intensity: f32

Sub-surface scattering weight [0, 1].

emission_color: Vec3

Emission RGB (pre-tonemapped).

emission_strength: f32

Emission multiplier (values > 1 bloom-clip).

ior: f32

Index of refraction (for glass, water, cornea).

anisotropy: f32

GGX anisotropy [0, 1].

subsurface_color: Vec3

Subsurface tint colour.
