Struct ForwardDecalMaterialExt

pub struct ForwardDecalMaterialExt {
    pub depth_fade_factor: f32,
}

Material extension for a ForwardDecal.

In addition to wrapping your material type with this extension, your shader must use the bevy_pbr::decal::forward::get_forward_decal_info function.

The FORWARD_DECAL shader define will be made available to your shader so that you can gate the forward decal code behind an ifdef.

Fields

depth_fade_factor: f32

Controls the distance threshold for decal blending with surfaces.

This parameter determines how far away a surface can be before the decal no longer blends with it and instead renders with full opacity.

Lower values cause the decal to only blend with close surfaces, while higher values allow blending with more distant surfaces.

Units are in meters.

Trait Implementations

impl AsBindGroup for ForwardDecalMaterialExt

type Data = ()

Data that will be stored alongside the “prepared” bind group.

type Param = (Res<'static, RenderAssets<GpuImage>>, Res<'static, FallbackImage>, Res<'static, RenderAssets<GpuShaderStorageBuffer>>)

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

label

fn unprepared_bind_group( &self, layout: &BindGroupLayout, render_device: &RenderDevice, _: &mut <<ForwardDecalMaterialExt as AsBindGroup>::Param as SystemParam>::Item<'_, '_>, force_no_bindless: bool, ) -> Result<UnpreparedBindGroup<<ForwardDecalMaterialExt as AsBindGroup>::Data>, AsBindGroupError>

Returns a vec of (binding index, OwnedBindingResource).

fn bind_group_layout_entries( render_device: &RenderDevice, force_no_bindless: bool, ) -> Vec<BindGroupLayoutEntry>

Returns a vec of bind group layout entries.

fn bindless_descriptor() -> Option<BindlessDescriptor>

fn bindless_slot_count() -> Option<BindlessSlabResourceLimit>

The number of slots per bind group, if bindless mode is enabled.

fn bindless_supported(_: &RenderDevice) -> bool

True if the hardware actually supports bindless textures for this type, taking the device and driver capabilities into account.

fn as_bind_group( &self, layout: &BindGroupLayout, render_device: &RenderDevice, param: &mut <Self::Param as SystemParam>::Item<'_, '_>, ) -> Result<PreparedBindGroup<Self::Data>, AsBindGroupError>

Creates a bind group for self matching the layout defined in AsBindGroup::bind_group_layout.

fn bind_group_layout(render_device: &RenderDevice) -> BindGroupLayout

where Self: Sized,

Creates the bind group layout matching all bind groups returned by AsBindGroup::as_bind_group

impl AsBindGroupShaderType<ForwardDecalMaterialExtUniform> for ForwardDecalMaterialExt

fn as_bind_group_shader_type( &self, _images: &RenderAssets<GpuImage>, ) -> ForwardDecalMaterialExtUniform

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 ForwardDecalMaterialExt

fn clone(&self) -> ForwardDecalMaterialExt

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ForwardDecalMaterialExt

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for ForwardDecalMaterialExt

fn default() -> ForwardDecalMaterialExt

Returns the “default value” for a type.

impl MaterialExtension for ForwardDecalMaterialExt

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.
