You can add new fixed cameras by dropping the prefab FixedCamera in your scene (or instantiating it from the Level Design Tool ). The prefab contains a VirtualCamera and a Trigger. Once the player enters the trigger the camera will be activate.
Make sure you cover the desired area with the trigger. In this example, we want the camera to activate when the player enters the corridos so we make the trigger to cover that particular area.
Once the area has been covered you have to position your object POVVirtualCamera in the right angle. We have create a component called CameraPreview attached to the POVvirtualCamera object that will allow you to preview the camera. Remember that you can change the CinemachineVirtualCamera parameters, such as FOV to get the desired camera view.
The CameraPreview has two utility buttons that will help you setting up these camera angles.

Go To POV: Will move the editor camer to the VirtualCamera position and rotation.
Move to viewport POV: Will move the POV to the current editor position and rotation.
