struct

`SushiEngine::Render::Material`

A physically-based surface: its maps, its scalars, and its state.

Declared in: engine/domain/material/include/SushiEngine/material/material.hpp

The scalar fields double as tints when the matching map is set, matching glTF's factor semantics — albedo multiplies the base-colour map, and metallic/roughness multiply the packed map's blue and green channels.

Properties

`albedo`	Base colour tint / F0 tint when metallic.
`base_alpha`	Base colour alpha; drives cutout and blending.
`albedo_map`	sRGB base colour + alpha.
`metallic`	0 = dielectric, 1 = metal.
`roughness`	Microfacet roughness in (0, 1].
`metallic_roughness_map`	Packed metallic-roughness: G = roughness, B = metallic (glTF order).
`packed_occlusion`	The MR map is an ORM map whose red channel is ambient occlusion.
`normal_map`	Tangent-space normal; Z reconstructed.
`normal_scale`	Bump strength.
`height_map`	Height for parallax occlusion mapping.
`height_scale`	Displacement depth in UV-space units.
`parallax_steps`	March steps; 0 disables POM.
`parallax_shadows`	Self-shadow the surface along the light ray.
`parallax_silhouette_clip`	Discard where the ray leaves the height field.
`occlusion_map`	Ambient occlusion, red channel.
`occlusion_strength`	Blend toward unoccluded at 0.
`emissive`	Emissive colour, HDR.
`emissive_intensity`	Multiplies emissive and its map.
`emissive_map`	sRGB emissive.
`emissive_enabled`	Off means the emissive term is skipped.
`detail_albedo_map`	Overlaid close-up albedo detail.
`detail_normal_map`	Overlaid close-up normal detail.
`detail_mask_map`	Where the detail set applies.
`detail_normal_scale`	Detail bump strength.
`main_transform`	Tiling/offset for the base map set.
`detail_transform`	Tiling/offset for the detail set.
`anisotropy`	Stretches the specular lobe; 0 = isotropic.
`anisotropy_rotation`	Tangent-space rotation of the stretch, turns.
`clearcoat`	Strength of a second, smooth specular layer.
`clearcoat_roughness`
`sheen_color`	Retroreflective cloth rim.
`sheen_roughness`
`transmission`	Fraction of light passing through.
`subsurface_color`	Tint of transmitted light.
`thickness`	Distance light travels inside, metres.
`ior`	Index of refraction; drives dielectric F0.
`surface_type`
`alpha_cutoff`
`cull_mode`
`cast_shadows`
`anisotropic_filtering`	Sampler anisotropy, 1 = off.
`wrap_mode`	Sampler address mode for every map.
`weather_wettable`	Opts the surface into weather-driven wetness (design doc §5.3, W5): albedo darken / roughness drop.
