This type of placement allows you to remap a quad defined inside an image to a quad defined in Smode space.
To do that first click on "edit on" button in the visualizer, uncheck
Enable inside the parameters and click on
Reset Input.
Then you need to define the 4 key-points of the image on the input image.
Once finished check
Enable and click on
Reset Output.
You can now place the output quad as you wish in the visualizer.
