EnvironmentSettings class Lighting and environment

A copyable, interpolatable snapshot of a Scene's scene-wide look.

Read one with Scene.environmentSettings and apply one by assigning it back. lerp blends two snapshots: continuous fields (exposure, intensities, color-grading and post-effect parameters) interpolate; discrete fields (the image-based-lighting environment, skybox, sky lighting, sun light, tone mapping operator, and each effect's enabled flag) switch at the halfway point so the endpoints reproduce the inputs exactly. To cross-fade an effect on or off smoothly, animate its amount (e.g. bloom intensity) rather than relying on the flag.

A typical scripted transition drives t from an animation each frame:

scene.environmentSettings = EnvironmentSettings.lerp(dayLook, nightLook, t);

Most callers use Scene.environmentSettings or EnvironmentSettings.lerp instead of this directly.
EnvironmentSettings.fromScene(Scene scene): Reads the current look of scene into a snapshot. The IBL/sky references are shared (not deep-copied); the scalar look is captured by value.
