    pub enabled: bool,
    pub sun: bool,
    pub sun_dir: [f32; 3],
    pub sun_color: [f32; 3],
    pub sun_intensity: f32,

}

CPU.1 — the per-frame dynamic-light environment for one grid (grid-local). Mirror of the GPU shade_lit inputs. enabled == false (the default) keeps the baked-byte path. CPU.2 adds hard voxel shadows (sun + flagged point lights) via a per-(voxel,face) shadow march; shadow_strength == 0 (the Default) leaves the lighting diffuse-only.

Fields

enabled: bool

Whether dynamic lighting is active this frame (else the baked path).

sun: bool

Whether the sun is present.

sun_dir: [f32; 3]

Grid-local unit direction to the sun.

sun_color: [f32; 3]

sun_intensity: f32

sun_casts_shadow: bool

CPU.2 — whether the sun casts a hard shadow.

points: &'a [CpuPointLight]

Grid-local point lights.

ambient: [f32; 3]

Ambient multiplier on the baked byte (smooth mode’s fill).

bands: u32

Cel band count: 0 = smooth, ≥1 = quantize + gradient-map (stylized).

shadow_tint: [f32; 3]

Stylized ramp’s cool unlit-end tint (used when bands > 0).

shadow_strength: f32

CPU.2 — fraction of a caster’s light removed where a shadow ray is occluded (0 ⇒ shadows off, 1 ⇒ full black). A shadowed sample keeps 1 - shadow_strength of that caster.

shadow_bias: f32

CPU.2 — shadow-ray origin bias along the surface normal, voxel units (kills self-shadow acne). ~1.5 is a good default.

shadow_max_dist: f32

CPU.2 — sun shadow-ray length cap, voxel units (point-light rays stop at the light instead).
