Adding RTPC Curves to Blend Tracks

There are two ways to add RTPC curves to blend tracks:

  • Adding curves to the Blend Container itself.

  • Adding curves to each Blend Track within a Blend Container.

If you choose to add an RTPC to a Blend Container itself, that RTPC will be applied equally to all objects within the container. For more information on creating and working with RTPCs, refer to Working with RTPCs.

However, you can also add RTPCs to each blend track in a container. In this way, you can apply RTPCs to selected objects at a time. For example, say you've added all the collision sounds in a racing game to one Blend Track. If you add an RTPC to this blend track that varies volume according to impact force, the volume of each collision sound will be affected by this RTPC.

To add an RTPC curve to a blend track:

  1. In the Blend Container Property Editor, click Edit Blend Tracks to open the Blend Track Editor.

    [Tip] Tip

    You can also press Ctrl+Shift+T to access the Blend Track Editor.

    The blend tracks you have previously created are displayed.

  2. In the blend track to which you want to add RTPC curves, click the Property Selector button.

    A list of available sound properties is displayed.

  3. Click the sound property you want to be affected by the RTPC.

    An RTPC curve is displayed in the graph view.

  4. From the X axis list, click the Game Parameter that you want to assign to the Wwise property.

    The Game Parameter is assigned to the X axis in the graph view.

  5. Repeat these steps to add more RTPC curves to the graph.

    [Note] Note

    As you add multiple curves with different Game Parameter units, the units will disappear from the axes. However, you will still be able to see the units for any selected point displayed in the X axis and Y axis boxes below the graph.
