This gizmo creates the effect of an invisible object moving over a background of your choosing.

Inputs:

FG: The object to become invisible.

Matte: An additional matte to use (will defualt to FG alpha channel)

BG: The background to be distorted.

Output:

The node will output the distorted RGBA pass over the BG as default.

This is what I used as a FG test element, A static sphere with a colourwheel and noise used as texture and the noise driving a distortion:

 

This is the result using a checkerboard on the BG input.

 

 

Edge Tab

Edge Size Control:

    Blur: Blurs the edge selection.

Edge Distort Control:
    Distort Scale: Controls how much the distortion affects the background.
    Blur Amount: Controls how much the background is blurred based on the distortion.

    Intensity: Controls how much the distortion affects the background.
    Speed: Changes the speed or bubbling of the distortion.
    X/Y Size: Controls the size of the noise, the bigger, the further the distortion moves the background.
    Noise Blur: Softens the noise, creating softer distortion.

Core Distortion Control
    Distort Scale: Controls how much the distortion affects the background.
    Blur Amount: Controls how much the background is blurred based on the distortion.
    Luminance Effect Amount: Controls how the luminance of the FG object Affects the distortion. The Brighter the image the more it get distorted.

Concerning the 8.0 v06 bug. If you open the gizmo up in an editor you can delete the top lines that establish the Nuke version. The gizmo runs just fine without it.

Great gizmo BTW!
