We don’t use lightning for the terminal as that would kill the performance. Instead we use a special material on the textures, which does not react to light meaning it simply displays the texture as it is. For external structures we use another material, which reacts to the sun light. If we would not have this setup, the terminal would also go completely dark during the night. The system we have is designed so that can easily set correct lightning when something is inside and outside by just changing the material. To make the effect you suggests, we could add a light source to all doors, very much possible but will most likely take performance. Real time light is very expensive in Unity so we don’t want to add too much.
I understand your view but we don’t want to add this now when the game is not fully optimized yet.
