<mark style="background-color:red;">The Prop feature is currently in</mark> <mark style="background-color:red;"></mark><mark style="background-color:red;">**BETA**</mark><mark style="background-color:red;">. We are working on improving the attachment convenience for Trackers and adding support for more object types.</mark>

Click the **Add new prop** button to create a new Prop.\
Then, specify its **Type**. Currently, only **Cube** and **Sphere** are supported.

Assign a **Tracker** to track the Prop and define the size of the object:

* For a **Cube**, enter the width of the top face into **Width**, the depth into **Depth**, and the height into **Height**.
* For a **Sphere**, enter the diameter.

Since this feature uses only one Tracker, the Tracker must be attached to the designated position:

* For a **Cube**, when looking at the top face from above, attach the Tracker at the **bottom-left corner**, with the LED positioned on the top face. Use the bracket provided by default with the VIVE Tracker.
* For a **Sphere**, simply attach the Tracker at the **center of the ball**.

After entering all the values, click the **Calibration** button.
