Morphing between mask shapes

Hi,

Do you know a way to do a morphing between mask shapes with Fusion? I have seen this tutorial, and it seems so easy with After Effects:

My aim is to do morphing between different letters, for example to transform a "1" into "2"... Thank you for your help !

Without any plugins i'm not sure. All i can say is draw your spline around the most complex shape ,2 in your example and adjust it to the "1" shape at the first frame of your animation (create two texts as guides of course).
