World Markers
This system renders Navigation Markers on-screen via a canvas. The markers track to their position, and can scale/fade depending on the distance.

Setup
This system is managed by the NavigationWorldMarkerManager. The prefab can be found in the Core > Prefabs > Systems > Management folder. Drag that into your scene, as a child of the ExplorationToolkitManager and you should be good to go!
Note
This will require a NavigationManager as well in order to keep track of the markers placed in the world.
Marker Properties
The NavigationWorldMarkerManager GameObject has a canvas as a child. This is where the world marker UI elements will be housed. If you want to change the look of these world markers, you can modify the NavigationWorldMarkerUI prefab in the Core > Prefabs > UI > Navigation folder.
In the Inspector, you can implement both fade over distance and/or scale over distance. You can set a start and end distance, as well as a falloff curve.
