    Is it possible to set a shader up to exclude ambient/sky light? I model buildings and bake daylight into the scene. But the exterior of the building glows at night. Thanks.

    That's not the ambient light. You need to make a day lightmap, and a night lightmap, and blend between the two.

    Like Fishman said, it isn't ambient light that does that, it's your lightmap.

    But if anybody wants to ignore ambient light, simply use the noambient flag in your shader:

    Code (csharp):
    1. #pragma surface surf BlinnPhong noambient
