To Apply TurbDissolve and/or TurbWipe

Insert an image into the scene tree.
Go to the image’s texture editor and make sure that the texture Unit is set to 1 and the Inheritable option is active. This is your Image A in an A-B transition paradigm.
Place a child image underneath the first one. This is Image B.
In Image B’s texture editor, set the Unit to 2 and make sure that the Inheritable option is inactive.
Apply the Dissolve plug-in to the Image A (the parent image).
In the plug-in editor, first adjust the Transition, followed by the other parameters, as per your liking.
