Resets to the default values


Distortion allows you to alter the background image to better match the perspective in your model.



In Perspective Distortion, the left and rights sides of the image are always kept vertical, and when you move one corner up or down, the other corner on the same side is moved by the same amount.

This often make it easy to match the background image to a perspective view. If you want more control select Full Distortion which lets you move all 4 corners independently.
