The first step in organizing objects within your Blend Container is to create and name individual blend tracks.

The blend tracks you create remain empty until you populate them with objects. Each blend track in a Blend Container can contain up to 128 objects. One object can exist in multiple blend tracks at the same time, and one blend track might contain the same object multiple times. You can add and remove objects to and from blend tracks in the Contents Editor.

	Tip
	The order of objects in a blend track is important because it determines how they will be positioned for crossfading. For more information on crossfading, refer to Managing crossfades.

	Note
	To remove an object from a Blend Track, select the object and press Delete. This removes the object from the Blend Track list but does not remove the object from the Contents Editor.

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

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.

After you have added your RTPC curve or curves to a blend track, you can define them as you would any other RTPC curves. For example, you can add points, move them, or define curve segments. For information on how to do this, refer to Controlling property values using Game Parameters.

Each blend track of a Blend Container can contain multiple RTPC curves. Using the Blend Track Editor, you can work with multiple RTPC curves at once.

When you select an RTPC curve in RTPC list, it is highlighted in the graph view and can be edited. For information on working with RTPC curves, refer to Controlling property values using Game Parameters.
