Vertex Animation Tool & Timeline Meshes

Using the 3ds Max Animation Timeline in conjunction with the Vertex Animation tools to create a 2D Texture that stores the position of vertices in any given 3D mesh. I have accomplished this and it’s working in UE4. I want to know how to assign an action so that I can control this animation with a mouse click so that the object is stationary, then moves when I click on it during game play/runtime.

This is the tutorial that I used to do the Blueprint:

Attached you will find the programming for the material that activates the animation.

Thanks for your help in advance.
