Three new URP Volume Override tracks (Path A): ChromaticAberration (73): power → intensity, isEnable toggles effect. Per-channel redOffset/greenOffset/blueOffset not expressible in URP built-in CA. HdrBloom (38): bloomIntensity → Bloom.intensity, threshold → Bloom.threshold. Fields unconfirmed (no bundle data in 30-song scan). ColorCorrection (61): saturation (game 1.0=neutral) → ColorAdjustments.saturation (URP range -100..100). redCurve/greenCurve/blueCurve → ColorCurves via TextureCurve. Depth curves and selective color have no URP equivalent. Director.InitializeTimeline() acquires or creates a Volume on Camera.main and adds the required overrides programmatically.
