First pass on a system to fade objects that are occluding the player's view
For an item to be faded, it needs to be part of the hierarchy of a collider on the Resources layer AND tagged with the "Occlude" tag
When an item that passes these conditions is found it will be set to the FadeMaterial on the new CameraOcclusion component, and it's materials will be reverted once that item is no longer occluding the view
Manually tagged the leaves on the Birch and Oak trees - tagging isn't part of the model import process yet so this will need to be reapplied after a model update
The fade material is just a transparent standard shader, this could definitely be improved
