Blockout navigation improvement

In response to some feedback I recieved during the creation process, I have decided to improve the navigation of the level.

The main concern is that players are getting lost because they don't know where they have been.

This probably wont be as much of a problem later down the line when I add set dressing and clutter, but I have created a solution to allow players to see where they have been.

I created a blueprint actor with a trigger box, a light and some code to turn the light on when the player has been in the area.

This shows a subtle green spot on the ground in grid refs the player has already visited.

I populated the map with these objects as shown below:

In the next screenshot you can see how a player has taken an alternative path and exits a corridor not knowing which way to go, but as you can see, the path they have already taken is highlighted, so they know to go the other way!
