Unity 5: Materials blown out in scene (or missing) after building standalone

Good day,

I have been fighting with Unity 5’s building process for nearly two weeks. I have not found answers to resolve the problems occurring after building the scene to a standalone Mac version. I have taken a carefully long process to convert all my shaders to the default shader in Unity 5. I have deleted all other legacy materials. The scene looks fantastic when in edit and preview mode, but after building the scene, many of the colors are blown out. It almost appears like the color textures are missing and specular attributes are super hot! I have tried building with baked light maps and unbaked light maps. Yet, it seems not to change the outcome.

Errors after building:

Error 1:
Building - Failed to pack resource file: UnityEditor.HostView:OnGUI()

Attached is a screenshot of the blown out colors (which appears to be missing materials)

Figured out part of this issue. Real Time updates on reflection probes does not work! Once I switched to baked mode, all the materials appeared normal (minus the reflection from the probe).

Was abl;e to get the reflection probes working after unchecking the HDR check box and adjusting the intensity down.

There was a bug with realtime probes, that sometimes NAN values were being produced in cubemaps, so maybe it’s the same issue, check out upcoming 5.0b21, if you’ll still get that bug, please submit a bug with repro case and logs attached.

Thank you
