AR world dissolve effect in Unity

I have been trying out ARCore & ARKit using Unity’s ARFoundation. It allows you to utilize both ARKit and ARCore without having to write systems for each. This makes it a a nice layer of abstraction that allows for basic AR types to be setup; point cloud data, detected plane visualisation, and AR ray casting that is more efficient than normal physics ray casting. I thought it would be cool to dissolve the game world away to reveal the real world.
