Struct Light2dDesc 

pub struct Light2dDesc {
    pub lightmap_scale: f32,
    pub mask_size: u32,
    pub filter: TextureFilter,
    pub textures_gen: u64,
    pub budget: LightBudget,
}

Construction parameters for one Light2dPass.

Fields

lightmap_scale: f32

Light map resolution as a fraction of the render target, clamped to 0.25..=1.0. Half resolution is usually indistinguishable and a quarter of the memory.

mask_size: u32

Shadow mask edge in pixels, clamped to 64..=2048. The mask is stretched over each light’s footprint, so a smaller mask softens shadow edges and never moves a shadow.

filter: TextureFilter

Sampling for falloff textures; the shadow mask is always linear.

textures_gen: u64

Generation of the queued textures. Uploads are applied when it changes, so a game that queues its level’s textures once pays for them once.

budget: LightBudget

Per-frame limits, enforced by plan_lighting with typed issues.
