GpuDrivenTextures
The forward path's maps, as decode programs. SurfaceMaterial binds an albedo, a normal and
an occlusion-roughness-metallic image, and its scales and strengths mean what they mean there —
the ORM map replaces roughness and the scale gives the scaling back, and occlusion strength is
a mix from one rather than a multiply. Defaults are SurfaceMaterial's.
Explained in Hello world.

baseColourreadonlyoptional | GpuDrivenProgram | |
normalreadonlyoptional | GpuDrivenProgram | |
ormreadonlyoptional | GpuDrivenProgram | Occlusion in R, roughness in G, metallic in B — glTF's packing, as SurfaceMaterial.orm. |
emissivereadonlyoptional | GpuDrivenProgram | Where the surface glows, in colour, as SurfaceMaterial.emissive's map: the glow is the albedo
times this times the material's emissive, so a black texel glows nowhere and the scalar
still says how brightly the rest does. glTF's rule and flat/main.ts's, which the facade of
a city at dusk needed — lit windows in a wall that does not glow — and the pipeline could not
say until 2026-09-18. |
