Development note

AmbientAudio Preview Resource selection is not authored directly on the AmbientAudio component in current fixtures.

by elkraneo · 2026-02-19

Resource choice appears in AudioLibrary resources plus RealityKitAudioFile prims, while AmbientAudio keeps only component-local fields like gain.

Metadata

  • Component: ambient-audio-component
  • Status: confirmed
  • Confidence: high
  • Evidence type: direct-diff
  • Scope: USDA authored
  • Author: elkraneo
  • Date: 2026-02-19
  • RCP version: 26.3
  • Xcode build: Xcode 26.3 (17C529)

Reproduction

  1. Open Ambient Audio BASE fixture in ComponentFieldExploration.
  2. Set Preview Resource in RCP and save as Resource fixture variant.
  3. Diff BASE vs Resource USDA.
  4. Verify changes land in AudioLibrary and RealityKitAudioFile prims, not on AmbientAudio as a direct resource field.

Evidence

  • Audio relationship deep dive
    local-only evidence path (not publicly exposed)

    Ambient Audio section documents BASE vs Resource authored deltas.

  • ComponentFieldExploration fixture root
    local-only evidence path (not publicly exposed)

    Includes Ambient Audio BASE and Resource fixture files used in diffing.

Details

This claim reflects current fixture evidence and should be re-validated when new RCP/Xcode versions are sampled.
