    Hello,

    Looking at the new Unity 5 I read that the shadows were now available on Windows Phone:

    "Shadows on windows mobile devices now work just like on iOS / Android - no cascaded shadow maps (ie not" too slow on mobile "anymore)."

    So in my szene Unity 5, I activated the "baking" for the statics shadows.
    In my Unity szene my shadows are visible, but when I export Windows phone (Windows phone store 8.1), I have no light on my game, no shadows.

    While the game on Android out shadows and lighting.
    In my Android and Windows rendering quality parameters have the same options.

    I want to know what I'm missing for Windows phone the lighting.

    What device you're testing on, due driver errors shadows are automatically disabled on the following GPUs:
    Adreno 225
    Adreno 305
    Adreno 330

    Snapdragon 800 has Adreno 330 inside.
    Snapdragon S4 has Adreno 225 inside.

    The notes are unfortunate - the change for cascaded shadow maps was made much earlier before we discovered that shadows sometimes crash drivers on those devices. Realistically, you wouldn't want to use real time shadows on any real game because these mobile devices are simply too slow for that.

    So there is no way to have shadows on Windows Phone?

    Why you do not do a similar shade system that script directly in Unity that will activate when selecting Windows Phone ?

    Because this technique is not general enough and doesn't work in all scenarios (for example, there's no self-shadowing).

    Clarifying question. Is it possible to make baked static lightmaps to work on Windows Phone 8 and Unity 5?

    Doesn't work in our case... Is there something magic? Worked with Unity 4.

    Yes, and on ios and android as well. Switching from directional to non directional seems to work.

    One thing to note, Realtime GI doesn't work on Windows Phone 8, try disabling it in Lighting window, so you can see same results in Editor and WP8, maybe that's the problem

    Same thing here, made a bug report. To fix this you can change Directional Mode to Non Directional in General GI settings (lighting), otherwise use Mobile/Unlit (supports lightmap) shader. Also if you change application focus (something like alt tab but for Windows Phone) it stops working, gives the "Trying to reload asset from disk that is not stored on disk" error, and then all gameobjects that were using lightmap becomes completely black. (Lumia 920 - GPU Adreno 225)

    Same problem here.
    Directional lightmaps don't work on Windows Phone 8.1, but they do work on Android normally.
    Changing to Non-Directional lightmaps work normal on both devices.

    I have made a bug report.
    My testing device is Nokia Lumia 822 with Adreno 225

    Hope this get fixed soon.

    Edit:
    Please vote on this issue so it gets fixed sooner.
