Figured it out, it only works with Sprite Renderer, it will not work with Image.... WOW. That sucks.
They need some actual documentation for this thing. Or a series of tutorials that are actually informative on the basic functions / use of this plug in.
Baby steps. Then giant card tutorials. That would be great. How to apply an effect and have it fade in and out, with clear instructions, showing everything from what kind of image it can use, to how the effects are setup, to how to control them. Basic stuff. This doesn't have that really.
