Physical material parameters for PBR lighting.

Fields

albedo: Vec3

Base color / albedo (linear sRGB).

alpha: f32

Alpha channel (0 = fully transparent, 1 = opaque).

metallic: f32

Metallic factor [0,1]: 0 = dielectric, 1 = conductor.

roughness: f32

Roughness factor [0,1]: 0 = mirror, 1 = fully diffuse.

ao: f32

Ambient occlusion factor [0,1].

emissive: Vec3

Emissive color (added on top of lighting).

ior: f32

Index of refraction (used for Fresnel, default 1.5 for dielectrics).

anisotropy: f32

Anisotropy amount [-1,1]: positive = horizontal highlight stretch.

anisotropy_dir: Vec3

Anisotropy tangent direction.

clearcoat: f32

Clear-coat layer intensity [0,1].

clearcoat_rough: f32

Clear-coat roughness [0,1].

sss_color: Vec3

Subsurface scattering color.

sss_radius: f32

Subsurface scattering radius.
