Struct PbrMaterial 

pub struct PbrMaterial {
    pub label: String,
    pub albedo: (f32, f32, f32, f32),
    pub albedo_t: Option<Handle<Texture>>,
    pub metallic: f32,
    pub roughness: f32,
    pub metallic_roughness_t: Option<Handle<Texture>>,
    pub normal_t: Option<Handle<Texture>>,
    pub occlusion_t: Option<Handle<Texture>>,
    pub uniform_buffer: Option<Handle<Buffer>>,
}

Describes a physically based rendering material. It contains the material properties such as albedo color, metallic and roughness intensity, as well as the textures for these properties. It also contains a uniform buffer that is automatically created and updated with the material data, which can be used in the shader to access the material properties. The PbrMaterial3d component is a wrapper around a handle to a PbrMaterial asset, which also adds the [PbrSsboTransformMarker] to the entity, indicating that its transform should be included in the PbrSsboTransform updates.

Fields

label: String

albedo: (f32, f32, f32, f32)

The albedo color of the material instance (r, g, b). The alpha channel is unused.

albedo_t: Option<Handle<Texture>>

The albedo texture of the material instance. If None, the material will use the albedo color.

metallic: f32

The metallic intensity of the material instance.

roughness: f32

The roughness intensity of the material instance.

metallic_roughness_t: Option<Handle<Texture>>

The metallic-roughness texture of the material instance. If None, the material will use the metallic and roughness scalar intensity. The metallic value is stored in the blue channel, and the roughness value is stored in the green channel.

normal_t: Option<Handle<Texture>>

The normal texture of the material instance. The normal map is expected to be in tangent space. The alpha channel is unused.

occlusion_t: Option<Handle<Texture>>

The occlusion texture of the material instance. The occlusion value is stored in the red channel.

uniform_buffer: Option<Handle<Buffer>>

The buffer containing the material data. It is automatically created and updated if not set.

Trait Implementations

impl Clone for PbrMaterial

fn clone(&self) -> PbrMaterial

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for PbrMaterial

fn default() -> Self

Returns the “default value” for a type.

impl RenderBinding for PbrMaterial

type Params = (Res<'static, AssetServer>, Res<'static, PlaceholderTexture>)

fn describe( &mut self, (asset_server, placeholder_tex): &SystemParamItem<'_, '_, Self::Params>, builder: &mut RenderBindingBuilder, )

Describes the render binding. This is used to specify the RenderData that should be used to create the bind group layout and bind group entries, and to specify the binding index for each buffer and texture.

fn label(&self) -> &str

Whether the gpu asset should be recreated. This is called every frame. The default is to never recreate (None).

impl TypePath for PbrMaterial

fn type_path() -> &'static str

Returns the fully qualified path of the underlying type.

fn short_type_path() -> &'static str

Returns a short, pretty-print enabled path to the type.

fn type_ident() -> Option<&'static str>

Returns the name of the type, or None if it is anonymous.

fn crate_name() -> Option<&'static str>

Returns the name of the crate the type is in, or None if it is anonymous.

fn module_path() -> Option<&'static str>

Returns the path to the module the type is in, or None if it is anonymous.

impl VisitAssetDependencies for PbrMaterial

fn visit_dependencies(&self, visit: &mut impl FnMut(UntypedAssetId))

impl Asset for PbrMaterial
