readShadowRadius

readShadowRadius(): Node <"float">

Defined in: packages/three-flatland/src/materials/instanceAttributes.ts:77

Read the per-instance shadow-occluder radius from instanceExtras.x. World units. Auto-resolved each frame to max(|scale.x|, |scale.y|) by transformSyncSystem, overridable via Sprite2D.shadowRadius.

Shadow-casting LightEffects consume this value for algorithm- specific purposes — SDF sphere-tracers use it as the self-silhouette escape distance; future shadow maps would use it for depth bias; AO passes could use it for sample radius.

Returns
