Struct MaterialProperties

pub struct MaterialProperties {

Common Material properties, calculated for a specific material instance.

Fields

render_method: OpaqueRendererMethod

Is this material should be rendered by the deferred renderer when. AlphaMode::Opaque or AlphaMode::Mask

alpha_mode: AlphaMode

The AlphaMode of this material.

mesh_pipeline_key_bits: MeshPipelineKey

The bits in the MeshPipelineKey for this material.

These are precalculated so that we can just “or” them together in queue_material_meshes.

depth_bias: f32

Add a bias to the view depth of the mesh which can be used to force a specific render order for meshes with equal depth, to avoid z-fighting. The bias is in depth-texture units so large values may be needed to overcome small depth differences.

reads_view_transmission_texture: bool

Whether the material would like to read from ViewTransmissionTexture.

This allows taking color output from the Opaque3d pass as an input, (for screen-space transmission) but requires rendering to take place in a separate Transmissive3d pass.
