Face Deformer Projecting Random Shapes

Hey Everyone, Just been playing around with the face deformer and I can’t make it actually deformer the 3d meshes in any way other than it just spitting out some random shapes. I have tried with both external 3d meshes and the one provided by Notch themselves. Not sure if there is anything I am missing to make the mesh deform properly as I am talking or is what I am doing more of a rigging thing that I would need a specific mesh for and an animation program like blender?

Thanks in advance!
