You can call the function POIShowBeacon to quickly visualize a given POI in front of the player. Or call POIShowBeacon without passing any POI and all visible POI in the compass bar will illuminate briefly. Example:
All beacons use the same material, located in Resources/Materials/Beacon. If you want to change the color or any other material properties. feel free to edit this material.
You can specify a sound effect when showing beacons in the CompassPro script or for each POI script (see previous sections).
