A subset of the Material trait for defining extensions to a base Material, such as the builtin StandardMaterial. A user type implementing the trait should be used as the E generic param in an ExtendedMaterial struct.

Provided Methods

fn vertex_shader() -> ShaderRef

Returns this material’s vertex shader. If ShaderRef::Default is returned, the base material mesh vertex shader will be used.

fn fragment_shader() -> ShaderRef

Returns this material’s fragment shader. If ShaderRef::Default is returned, the base material mesh fragment shader will be used.

fn prepass_vertex_shader() -> ShaderRef

Returns this material’s prepass vertex shader. If ShaderRef::Default is returned, the base material prepass vertex shader will be used.

fn prepass_fragment_shader() -> ShaderRef

Returns this material’s prepass fragment shader. If ShaderRef::Default is returned, the base material prepass fragment shader will be used.

fn deferred_vertex_shader() -> ShaderRef

Returns this material’s deferred vertex shader. If ShaderRef::Default is returned, the base material deferred vertex shader will be used.

fn deferred_fragment_shader() -> ShaderRef

Returns this material’s prepass fragment shader. If ShaderRef::Default is returned, the base material deferred fragment shader will be used.

fn specialize( pipeline: &MaterialExtensionPipeline, descriptor: &mut RenderPipelineDescriptor, layout: &Hashed<InnerMeshVertexBufferLayout>, key: MaterialExtensionKey<Self> ) -> Result<(), SpecializedMeshPipelineError>

Customizes the default RenderPipelineDescriptor for a specific entity using the entity’s MaterialPipelineKey and MeshVertexBufferLayout as input. Specialization for the base material is applied before this function is called.
