Struct SpriteInstance 

pub struct SpriteInstance {
    pub model_id: u32,
    pub transform: SpriteInstanceTransform,
    pub material: u8,
    pub alpha_mul: u8,
    pub flags: u32,
    pub tint: u32,
}

One sprite instance: a model reference + world pose.

Fields

model_id: u32

LOD-chain id from SpriteModelRegistry::add / add_lod — which model this instance draws. The per-frame cull substitutes the distance-picked concrete mip entry.

transform: SpriteInstanceTransform

World pose: inverse model→world rotation/scale + position (see SpriteInstanceTransform::from_sprite).

material: u8

Voxel-material id (TV stage): indexes the renderer’s global material palette for this instance’s opacity + blend mode. 0 (the default) is opaque, so an unset instance renders unchanged.

alpha_mul: u8

Per-instance alpha multiplier (TV stage), 0..=255 (255 = unscaled, the default).

flags: u32

XS.4 — sprite shadow flags (roxlap_formats::sprite bits 4/5: NO_SHADOW_CAST / NO_SHADOW_RECEIVE). 0 (default) ⇒ casts + receives. Only honoured when the device is sprite-shadow capable.

tint: u32

Per-instance RGB tint, packed 0x00RRGGBB (white 0x00FF_FFFF = no-op).

Implementations

impl SpriteInstance

pub fn new(model_id: u32, transform: SpriteInstanceTransform) -> Self

A model reference + pose with the default opaque material (material = 0, alpha_mul = 255), shadows on (flags = 0), and no tint (0x00FF_FFFF).
