 ===== Adding Basic Lighting for Editing =====
-To work inside the editor, add temporary lighting:
+To work comfortably inside the editor, SubwaySim 2 provides a dedicated **editor-only lighting setup**.
+Instead of manually placing individual lighting actors, we use a predefined Blueprint called **BP_Sky**.
-  * **SkyAtmosphere**
+This Blueprint contains the complete temporary lighting setup required for editing maps inside Unreal Engine.
-  * **Directional Light**
-  * **Skylight**
-Add them via the green **Add ( + )** button.
+To add editor lighting:
+  * Open the **Content Drawer**
+  * Navigate to the following path inside the **SubwaySim2_Modding** plugin:
+SubwaySim2_Modding / GameFramework / EditorTimeOnly
+  * Drag **BP_Sky** into your level
 {{:manual:subwaysim:map_construction:createlevel2.png?direct&1000|}}
+Once placed, the Blueprint automatically provides:
+  * Sky atmosphere
+  * Sun / directional lighting
+  * Ambient skylight
+This lighting setup allows you to properly see and edit your map while working in the editor.

-Because SubwaySim 2 uses its own Core lighting system, lighting placed in your modded map will appear *in addition* to the game's lighting and will not react to in-game time.
+SubwaySim 2 uses its own internal Core lighting system at runtime.
-For development purposes, you can still use temporary lighting in the editor.
+For licensing reasons, this system cannot be included in the Modding SDK.
+The **BP_Sky** Blueprint is therefore used only for editor work.
+When the map is loaded in the game, this Blueprint is automatically removed and replaced by the game's native lighting system.

-For more realistic preview lighting, enable **Real Time Capture** in the Skylight settings.
+You can use the settings inside **BP_Sky** to roughly preview different times of day while editing.
+These changes are only visual aids for development and do not affect the final in-game lighting.
-Adjust the **Directional Light** rotation (Y- and Z-axis) to simulate different times of day.

-===== Disabling Editor Lighting Before Export =====
+===== Editor Lighting Behavior in Game =====
-Before exporting your map to SubwaySim 2, these editor lights must be disabled so they do not appear in the game.
-To do this:
+No additional steps are required to disable editor lighting before exporting the map.
-  * Select **SkyAtmosphere**, **Directional Light**, and **Skylight**.
+Although BP_Sky is used as an editor lighting helper, it must not remain active during gameplay, as it would conflict with SubwaySim 2’s internal lighting system.
-  * In the Details panel, disable **Visible**.
-This hides the lights in the game while keeping them available for further editing.
+For this reason, **BP_Sky destroys itself at runtime**:
-When editing again, simply enable **Visible** to restore the lighting.
+  * Inside the BP_Sky Blueprint, the **Event BeginPlay** triggers a **Destroy Actor** node.
+  * This ensures that BP_Sky exists only for editing inside Unreal Engine, but is removed immediately when the level starts running.
-{{:manual:subwaysim:map_construction:createlevel9.png?direct&700|}}
+This ensures that:
+  * The editor lighting setup never remains active in the final game
+  * The in-game lighting system remains fully controlled by SubwaySim 2
