Variable: MAX_SHADOW_MASK_LIGHTS

const MAX_SHADOW_MASK_LIGHTS: 32 = 32

Defined in: libs/scene/src/values.ts:81

Max number of shadow-casting lights backed by the screen-space shadow mask.

Each mask layer packs 4 lights (one per RGBA8 channel), so this maps to MAX_SHADOW_MASK_LIGHTS / 4 texture array layers. Shadow-casting lights are placed at the head of the clustered light buffer (indices 1..N), so this value must not exceed MAX_CLUSTERED_LIGHTS. Shadow lights beyond this cap fall back to being lit without a mask-backed shadow.
