Once activated on the <mark style="color:yellow;">**`UserTrack`**</mark> node, a GamePad Control button appears in the right-down corner of the Nodegraph, indicating that the GamePad controls are ready for use.&#x20;

To utilize it, hover the mouse over the GamePad button to access the controls.&#x20;

### GamePad Controls&#x20;

#### Camera Movement&#x20;

Use `W`, `A`, `S`, `D`, `E`, `Q` keys to control the translation movement of the camera (forward, left, backward, right, ascend, descend). While holding the right mouse button, press abovementioned keyboard keys to navigate the camera.&#x20;

#### Camera Orientation

While holding the right mouse button, move the mouse to control the yaw, pitch, roll, and tilt of the camera.
