Sometimes the surfaces your projector is aiming at will not be perfectly rectangular in snapshots. In the below image, there is a rectangular board which we wish to dress up as a 'present'. However, because the projector is angled away from the board, it does not appear rectangular in the snapshot.
In order to 'map' your rectangular media resources to these surfaces you can use the 'Skew' tool.
How To Use The Skew Tool
1. Select the media resource that you wish to skew.
2. In the righthand toolbar, select 'SKEW'
3. Drag the nodes at the four corners of the resource to the desired positions.
When projected, the present image will now map correctly to the board.
