So, how does the Morph transition effect in PowerPoint work? You duplicate a slide and then modify the existing slide objects so that a tween effect is created based on the differences between two or more slides. You can also create your own shapes to Morph rather than use PowerPoint’s pre-built shapes. However, what if you take two completely different slides and apply the Morph transition effect? The results will be unpredictable because although PowerPoint does have artificial intelligence, it still cannot define which objects should morph from the first slide to the second slide. To overcome this problem, PowerPoint allows you to use exclamation-named objects in your slides.
