How do I show physical transformations?

Hello,

I’m using Unreal Engine for short film development and I’m stuck on transformation. The long and the short of it is: I want to show a character undergo a physical change (like grow a few feet bigger or shrink their head) onscreen, but I have no idea how to do this without creating a normal 3D model and a “Change” model and switching between them out-of-shot.

Can someone please give me a better solution?

Morph Targets. You simply duplicate your Model in your 3D App and assign this morph target to your original model (In 3Ds Max you do this via the Morpher Modifier)
Morph Targets allow you to change the Positions of vertices with a single Value. This value can be accessed in Sequencer and your Blueprints.
However, you can’t add or remove Vertices. You can only change their position.
