The best way to add an infinite loop is to make use of the 'Slideshow'
component. Slideshows rotate through their contents, so if a slideshow
only contains a single Canvas then the contents of this Canvas will
repeat after the time period set on the Slideshow.
First add a Slideshow to a new effect. Then add a Canvas directly
afterwards. Now design your effect inside the Canvas, and you should
find you are able to set it to repeat. For an example, please see
