ludus::content::scene_format::LightingRecord¶

Struct

Version 3 to 6 trailer followed by LightCount LightRecords, then optional HDR RGB. Environment pixels are equirectangular, rows north to south, with linear RGB radiance in nits multiplied by EnvironmentRgb. Zero dimensions select the constant EnvironmentRgb radiance; zero RGB means no authored environment.
