Struct MaterialUniforms

#[repr(C)]pub struct MaterialUniforms {
    pub base_color: LinearRgba,
    pub emissive: LinearRgba,
    pub ambient: LinearRgba,
    pub pbr_factors: [f32; 4],
}

Expand description

Data for a material’s properties, formatted for the standard Lit Shader.

Mirrors the WGSL MaterialUniforms struct in khora-lanes/src/render_lane/shaders/lib/std/material.wgsl (#[repr(C)]); changing the field order or types here MUST be mirrored WGSL-side in lockstep.

Fields§

§base_color: LinearRgba

Base color of the material (linear RGBA).

§emissive: LinearRgba

Emissive color (rgb) and Specular Power (a).

§ambient: LinearRgba

Ambient color (rgb) and Padding (a).

§pbr_factors: [f32; 4]

PBR scalar factors, packed as [metallic, roughness, alpha_cutoff, _reserved].

The metallic-roughness texture (when present) is multiplied by metallic/roughness; with the white fallback texture these factors pass through unchanged.

Implementations§

impl MaterialUniforms

pub const METALLIC: usize = 0

Index into pbr_factors for the metallic factor.

pub const ROUGHNESS: usize = 1

Index into pbr_factors for the roughness factor.

pub const ALPHA_CUTOFF: usize = 2

Index into pbr_factors for the alpha-cutoff threshold.
