    If I bake the scene with directional light shadows on, the scene becomes dark, I have to remove shadows from the directional light for it to look normal.
    In 5.4.0 it was fine, I had baked the same scene with directional light shadows on and after it was done, it looked good as it suppose to be and the directional light still had the shadows turned on.

    So I had my static objects baked, and none static receive real time shadows.
    I can't seem to be able to do that anymore!!!

    Any idea?

    Unity 5.4.3?

    It sounds like this issue: ISSUE LINK

    It has been fixed but hasn't been put into a release yet. You can work around it for the moment by changing the line in UnityGlobalIllumination.cginc from:

    #define IMPROVED_BAKED_AND_REALTIME_SHADOW_MIXING 1

    to

    #define IMPROVED_BAKED_AND_REALTIME_SHADOW_MIXING 0

    Corrected the link for you.

    The file can be found in:

    {unity install path}/Data/CGIncludes/Lighting.cginc on windows

    /Applications/Unity/Unity.app/Contents/CGIncludes/Lighting.cginc on Mac

    That didn't do anything, still in the scene after baking directional light is darkening the scene if it had the shows on.
    I tried to close Unity, reopen, rebake, nothing helped.

    corrected this;
    UnityGlobalIllumination.cginc from:

    #define IMPROVED_BAKED_AND_REALTIME_SHADOW_MIXING 1

    to

    #define IMPROVED_BAKED_AND_REALTIME_SHADOW_MIXING 0

    ah, today i loaded up another project , and it seems to work , so i think you have to open a another project first, then close it, open the project at hand, and the fix will be applied.

    So this workaround seems to be working.

    Doing a Reimport on the whole project should also compile the shaders correctly if you don't want to switch projects.
