Struct gltf_json::material::PbrMetallicRoughness

pub struct PbrMetallicRoughness {
    pub base_color_factor: PbrBaseColorFactor,
    pub base_color_texture: Option<Info>,
    pub metallic_factor: StrengthFactor,
    pub roughness_factor: StrengthFactor,
    pub metallic_roughness_texture: Option<Info>,
    pub extensions: Option<PbrMetallicRoughness>,
    pub extras: Extras,
}

A set of parameter values that are used to define the metallic-roughness material model from Physically-Based Rendering (PBR) methodology.

Fields

base_color_factor: PbrBaseColorFactor

The material’s base color factor.

base_color_texture: Option<Info>

The base color texture.

metallic_factor: StrengthFactor

The metalness of the material.

roughness_factor: StrengthFactor

The roughness of the material.

• A value of 1.0 means the material is completely rough.
• A value of 0.0 means the material is completely smooth.

metallic_roughness_texture: Option<Info>

The metallic-roughness texture.

This texture has two components:

The metalness values are sampled from the B channel. The roughness values are sampled from the G channel. These values are linear. If other channels are present (R or A), they are ignored for metallic-roughness calculations.

extensions: Option<PbrMetallicRoughness>

Extension specific data.

extras: Extras

Optional application specific data.
