Struct SpriteShade 

pub struct SpriteShade<'a> {
    pub materials: &'a MaterialTable,
    pub material: u8,
    pub alpha_mul: u8,
    pub lights: CpuLights<'a>,
    pub shadow: Option<&'a dyn WorldOccluder>,
}

Material context for a translucent sprite draw (TV stage): the global MaterialTable plus this instance’s uniform material id and per-frame alpha multiplier. Passed (as Some) to draw_sprite_dense_shaded / ClipFlipbook::draw_frame_shaded to enable front-to-back accumulate-and-continue compositing; None (or an all-opaque effective material) takes the existing first-hit opaque path byte-for-byte.

Fields

materials: &'a MaterialTable

Global voxel-material palette (per-voxel id → opacity + blend mode).

material: u8

Uniform material id for every voxel of this sprite whose dense per-voxel mat array is empty (the TV.1 whole-sprite material).

alpha_mul: u8

Per-instance opacity multiplier (255 = unscaled), so an effect can fade out by cheap per-frame updates without re-uploading the volume.

lights: CpuLights<'a>

DL.7 — world-space dynamic lights. When enabled, the opaque hit is lit (sun + point lights + cel + ramp, flat per voxel) instead of the baked shade. CpuLights::default() (disabled) ⇒ unchanged.

shadow: Option<&'a dyn WorldOccluder>

XS.2 — world-space scene occluder for sprites receiving hard shadows: a lit sprite voxel marches a shadow ray (world space) against this and is darkened where terrain / other sprites block the caster. None (the default) ⇒ unshadowed sprites (the pre-XS.2 look).
