Available on crate feature bevy_pbr only.

The GPU representation of the uniform data of a StandardMaterial.

Fields

base_color: Vec4

Doubles as diffuse albedo for non-metallic, specular for metallic and a mix for everything in between.

emissive: Vec4

attenuation_color: Vec4

Color white light takes after traveling through the attenuation distance underneath the material surface

uv_transform: Mat3

The transform applied to the UVs corresponding to ATTRIBUTE_UV_0 on the mesh before sampling. Default is identity.

reflectance: Vec3

Specular intensity for non-metals on a linear scale of [0.0, 1.0] defaults to 0.5 which is mapped to 4% reflectance in the shader

roughness: f32

Linear perceptual roughness, clamped to [0.089, 1.0] in the shader Defaults to minimum of 0.089

metallic: f32

From [0.0, 1.0], dielectric to pure metallic

diffuse_transmission: f32

Amount of diffuse light transmitted through the material

specular_transmission: f32

Amount of specular light transmitted through the material

thickness: f32

Thickness of the volume underneath the material surface

ior: f32

Index of Refraction

attenuation_distance: f32

How far light travels through the volume underneath the material surface before being absorbed

clearcoat: f32

clearcoat_perceptual_roughness: f32

anisotropy_strength: f32

anisotropy_rotation: Vec2

flags: u32

The StandardMaterialFlags accessible in the wgsl shader.

alpha_cutoff: f32

When the alpha mode mask flag is set, any base color alpha above this cutoff means fully opaque, and any below means fully transparent.

parallax_depth_scale: f32

The depth of the StandardMaterial::depth_map to apply.

max_parallax_layer_count: f32

In how many layers to split the depth maps for Steep parallax mapping.

If your parallax_depth_scale is >0.1 and you are seeing jaggy edges, increase this value. However, this incurs a performance cost.

lightmap_exposure: f32

The exposure (brightness) level of the lightmap, if present.

max_relief_mapping_search_steps: u32

Using ParallaxMappingMethod::Relief, how many additional steps to use at most to find the depth value.

deferred_lighting_pass_id: u32

ID for specifying which deferred lighting pass should be used for rendering this material, if any.

Trait Implementations

impl AsBindGroupShaderType<StandardMaterialUniform> for StandardMaterial

fn as_bind_group_shader_type( &self, images: &RenderAssets<GpuImage>, ) -> StandardMaterialUniform

Return the T ShaderType for self. When used in AsBindGroup derives, it is safe to assume that all images in self exist.

impl Clone for StandardMaterialUniform

fn clone(&self) -> StandardMaterialUniform

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
