Change size of static points as a function of distance to camera

Now points have a fixed size so when we are close to them (or the FOV is small) they look massive hiding the terrain below. By making them smaller as a function of distance to camera this can be overcome.

This will not work when we have two cameras. Maybe add a normal point and move normal Points to a different layer?
