Getting Started with Acoustic Ray Tracing for Unreal

• Setup your project to use Acoustic Ray Tracing.
• Understand the general steps to hear the rendered acoustics.
• Understand the general steps to adjust the automatically generated acoustics.

• Unreal Native
• FMOD for Unreal
• Wwise for Unreal

1. Check you have a spatial audio source with Enable Acoustics as described by your platform: unreal Native, unreal and FMOD, unreal and Wwise
2. Check your audio source is passing through the Reverb plugin as described by your platform: unreal Native, unreal and FMOD, unreal and Wwise

1. Create an empty game object in the scene and add a MetaXRAcousticGeometry component to it. This is the parent object.
2. Make sure Include Child Meshes in this component is checked.
3. Create geometry in the scene using a static mesh (for example, a .fbx file), or 3D objects such as cubes, and attach them as child objects. As a simple example, create a floor, four walls, and a ceiling.
4. Create a new empty object and add a MetaXRAcousticMap component to it. Ensure the transform of this object has no Scale on its transform.
5. Click Bake Acoustics on the MetaXRAcousticMap component. By default, this will also bake the Acoustic Geometry. Line gizmos will appear to show the acoustic mesh outline and Sphere gizmos will appear to show the acoustic precompute points in the acoustic map.
6. Each time any part of your game mesh object changes, click Bake Acoustics again on the acoustic mesh to keep it current with the latest geometry in the scene.
7. Press play to hear acoustics audio.
