Skybox/SkyLight are now Actor-carried components instead of resident global settings, matching UE where SkyAtmosphere/SkyLight/fog are Actors added from Place Actors and configured in Details. - New SkyboxComponent (active + envPath asset slot) and SkyLightComponent (active + ambientColor); first-active entity wins per frame - SceneRenderer collects env from components into FrameSceneData (DrawSkybox/envPath/ambient); Renderer performs delta sync - env reloads only when the resolved path changes, neutral fallback when empty or unloadable - App-side env plumbing removed: kEnvPaths table and getEnvIndex/ setEnvIndex callbacks deleted; StatsPanel keeps ClearColor + debug view, env params move to Details - Serializer: scene-level Settings stores ClearColor only; env components serialize per entity; legacy v1 scenes (Environment header + Settings.AmbientColor/DrawSkybox) auto-migrate into an Environment entity on load for visual parity - Inspector: Skybox/Sky Light sections with .hdr asset slot dropdown and Add Component entries; Outliner "+ Create" popup offers Empty/Light/Camera/Environment
