Interface SceneEnvironmentDescriptor

Ground color (sRGB) lighting from -y (default: [0.24, 0.22, 0.2])

Environment radiance scale, 0..16 (default: 1)

Equirectangular environment texture id, 2:1; u = 0.5 faces -z, the top row is straight up. HDR maps (loadEnvironmentHdr / createEnvironmentFromFloat) are linear radiance, GGX prefiltered per roughness, with spherical-harmonics diffuse. LDR (sRGB) maps from loadTexture / createDataTexture need mipmaps (rough surfaces read blurrier mips). null (or 0) uses the sky / ground hemisphere, as do unknown or disposed ids.

Rotation of map around +y in radians (default: 0)

Sky color (sRGB) lighting from +y (default: [0.6, 0.66, 0.76])
