No GI (or Lightmaps) after a standalone build

    Hi
    I'm using a Forward Rendering Linear pipeline in Unity 5.4.1. I'm also using Precomputed Realtime GI and have fully baked my scene with all objects properly set to static. Everything looks perfect in both Scene and Game views!

    However, after I build a standalone executable, and try and run it, its as though someone turned the lights off. I can see some ambient light but NONE of my lighting has baked. I did some googling and discovered a possible issue with prefabs and lightmaps
    https://forum.unity3d.com/threads/problems-with-instantiating-baked-prefabs.324514/page-4
    but I've gone ahead and 'broken' ALL my prefabs BEFORE I do my bake.

    Is it possible it has something to do with the total size of all my textures or lightmaps?
    What are some troubleshooting steps?

    Any help appreciated!!!

    Have you tried enabling the 'auto' checkbox before you create your build?

    Having this issue now, figured I'd mention that enabling Auto didn't fix the issue for me.

    Hi

    Can you show me your Lighting Settings? Also, I need to clarify that we don't actually bake any lightmaps when using Realtime GI. We have data in the Lighting Data Asset which together with the objects and the lights quickly bakes indirect lightmaps during runtime. So for example, when you go to your preview window and view the Realtime Indirect for example, that texture is generated on the fly and is dependant on how the lights and materials are. If you change the intensity or color of your lights, or the material of your static object, the lightmap will be regenerated and different. Hope that answers some of your questions, and lets discuss more once I know your settings.

    That's weird for me why it should work nicely in the editor but not after building the game :confused:

    Would it be possible for you to make a very tiny example projects and file a bug to us? Seems like something a lot of people have issues with. Maybe it is a bug, or a workflow that isn't clear enough, but would be good to investigate.

    Thanks!

    I'm sorry It was a mistake on my side! I didn't mentioned when I'm working with multi-scene the light map settings will be saved on the active scene but I combined all the scenes inside another scene that didn't had lightmap enabled :oops::rolleyes:

    Too bad we can't build multi-scene into one scene after building the game.

    Glad to hear that you resolved it :) And yes, the multi-scene bit can be a bit tricky in terms of lighting, especially if it happens during runtime where don't have any warning etc.
