No pictures this time, just a brief update. The lighting is now controlled by switches (although in some rooms its still automatic). This means that the player has to navigate a room in almost total darkness to reach the light. The switch and similar objective are lit by spotlights. Enemies are also lit and now carry torches, currently if they find the player they simply stop and watch them until the player moves away. My plan is to have the enemy vision increase significantly when the lights are switched on, in darkness its a 45 degree cone in-front of them which for the moment doesn’t take into account obstructions because I cant get Physics.Raycast to work properly.
