UMovieSceneComposableCameraPatchTrack

#include <MovieSceneComposableCameraPatchTrack.h>

Inherits: UMovieSceneNameableTrack

Root-level Sequencer track that drives Composable Camera Patches.

Each section on the track represents one Patch activation window (asset + params + parameter bag); when a section enters its TrueRange the runtime fires AddCameraPatch, when it exits ExpireCameraPatch fires.

Root track (no object binding) by design — Patches live on the Director resolved through PlayerIndex + ContextName on the section, mirroring the BP AddCameraPatch library entry. This avoids forcing designers to bind the track to the PCM (which is itself transient and hard to bind cleanly in Sequencer); the section's own properties carry the addressing info.

Multi-row support is on so designers can stack overlapping patches in the same track (different LayerIndex per section, sorted by PatchManager). Each section is independent — sections do not blend with each other; the patch compositor's LayerIndex order does. Easing on each section is enabled and fed into the patch's envelope (EnterDuration / ExitDuration overrides) by the TrackInstance.

Modeled on UMovieSceneCVarTrack: same ImportEntityImpl-via-section pattern, same per-section TrackInstance dispatch through the engine's UMovieSceneTrackInstanceSystem. Track itself stores no animation data — sections own everything.
