Camera
Drag the Igloo360Camera 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.
On the details panel of the Igloo360Camera, there is a drop down selection named "Object to Follow" which allows you to specify which actor in the scene the camera position should follow. Alternatively, if you uncheck "Follow Object" and the camera will follow the default player in the scene.
Within the Inspector for the igloo360Camera, there is a Gamma modifier slider. Change the value to 1.8 if using Laser projectors, or 2.2 if using Blub projectors. This can be configured post build so don't worry if you are unsure!
This will stop the colour looking dark, and faded.

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 output 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 output.
