    Realtime GI used with scenes loaded additively works in editor but doesn't work in build (Unity 2018.3.0b12). I made a sample project where three scenes are loaded from a script:

    1. "Main" scene that contains only the camera. This scene is loaded first in sync. `Single` mode.
    2. "Geometry" scene that contains a cube marked as `Lightmap Static`. Loaded sync. additively.
    3. "Lighting" scene that contains a plane marked as `Lightmap Static` and emissive material on it set to `Realtime`. Loaded sync. additively.

    Lighting settings:



    Build Settings:



    There's a `Loader` scene that has a button to load those scenes as described above.

    Code (CSharp):
    1. public class SceneLoader : MonoBehaviour
    2. {
    3.     public string Main;
    4.  
    5.     public string Geometry;
    6.  
    7.     public string Lighting;
    8.  
    9.     private void Awake()
    10.     {
    11.         SceneManager.sceneLoaded += SceneManagerOnSceneLoaded;
    12.  
    13.         DontDestroyOnLoad(gameObject);
    14.     }
    15.  
    16.     private void SceneManagerOnSceneLoaded(Scene scene, LoadSceneMode mode)
    17.     {
    18.         if (scene.name == "Main")
    19.         {
    20.             SceneManager.LoadScene(Geometry, LoadSceneMode.Additive);
    21.             SceneManager.LoadScene(Lighting, LoadSceneMode.Additive);
    22.         }
    23.     }
    24.  
    25.     private void OnGUI()
    26.     {
    27.         if (GUILayout.Button("Load Main scene"))
    28.         {
    29.             LoadMainScene();
    30.         }
    31.     }
    32.  
    33.     public void LoadMainScene()
    34.     {
    35.         SceneManager.LoadScene(Main, LoadSceneMode.Single);
    36.     }
    37. }
    Realtime GI was built from the `Main` scene (set as the active scene), where `Geometry` and `Lighting` were also loaded.

    When entering Play mode and loading scenes from the `Loader` scene, GI works as expected.



    After making a Windows build, GI in the player doesn't work.



    I tested exact same assets and settings in Unity 2017 LTS and the Realtime GI works there as expected.
    Test project: https://1drv.ms/u/s!ApyPqduXdyo-k5Ivp2IVK1RBvKDvfA

    Reproduction steps:
    - Open project in Unity 2018.3.0b12
    - Build the project for Windows. `Loader` scene should be the first scene to load.
    - Run the player. Press the "Load Main scene" button in the top-left corner
    - See that the Realtime GI is not affecting the cube
