In scenes tracked with AE's 3D camera tracker, the ground plane of your scene in most cases ends up as an oblique plane in 3D space. Orient World fixes this - with a single click you turn a layer into the ground plane of your scene and orient everything accordingly. Instead of setting a ground plane, you can also align your scene on walls. To tweak it even further, you can also manually move, rotate and scale your coordinate system in 3D space.
Furthermore, Orient World offers an intuitive visualization of the world center. You can turn it on or off with a single click.
Hint for use with The Foundry's Camera Tracker
In contrast to the camera tracker build into CS6, The Foundry's Camera Tracker creates a null object that all other layers are parented to. In order to make Orient World work with The Foundry's Camera Tracker, you need to delete this parent null before applying Orient World.
