punctualParamsTexture property
The per-frame parameters texture holding every additional analytic light
(point and spot lights, plus any directional lights past the first
shadowed one), one per RGBA32F row, or null when there are none. Built by
PunctualLightBuffer and shared across every lit draw this frame; a draw
reads only the rows its per-object index slice selects.
Implementation
final gpu.Texture? punctualParamsTexture;
