Struct bevy::pbr::ExtendedMaterial

pub struct ExtendedMaterial<B, E>{
    pub base: B,
    pub extension: E,
}
Expand description

A material that extends a base Material with additional shaders and data.

The data from both materials will be combined and made available to the shader so that shader functions built for the base material (and referencing the base material bindings) will work as expected, and custom alterations based on custom data can also be used.

If the extension E returns a non-default result from vertex_shader() it will be used in place of the base material’s vertex shader.

If the extension E returns a non-default result from fragment_shader() it will be used in place of the base fragment shader.

When used with StandardMaterial as the base, all the standard material fields are present, so the pbr_fragment shader functions can be called from the extension shader (see the extended_material example).

Trait Implementations§

impl<B, E> AsBindGroup for ExtendedMaterial<B, E>
