Camera
Drag the "Igloo360Camera_6" actor from Content > Igloo into your scene. This is the object which renders the 360 degree output and makes it available to the Igloo Warper Application.
...
To use the Igloo Player Pawn: In your GameMode settings, set the DefaultPawnClass to be IglooFlyingPawn.
Preview
Included in the package is an app for previewing the output of the 360 Camera, Igloo Preview. Press play in the Unreal Editor and you will scene the 360 degree out rendered to the Igloo Preview app.
Note - The view in Igloo preview does not apply the required distortion to the Unreal output, as such you will see discontinuation in the Imageoutput.
