Camera Deformer
Use this Deformer to deform an object based on a grid overlaid on top of the camera view. This is very useful to create free deformations that are static compared to the camera view. Think of it as using a smear tool, except it will deform the object's volumes.
For example, you can stretch objects as they approach the frame boundaries, or even Pose Morph the points of the Camera Deformer to mix the effects. Another example would be to use the Deformer to create quick squash & stretch on one or several objects.
To use the Camera Deformer, simply add it to your scene and drop it as a Child of the object to deform. To affect several objects at once, place the Deformer at the same level as the objects to deform, inside a Null Object. Select the Deformer and switch to Points mode to modify the Deformer's points and deform the object(s).
