We have recently noticed in our scene that normal maps applied to objects seemed to disappear when we baked them compared to when we lit them with realtime lights. I'm not sure if this is the expected behaviour or if we are doing something wrong but to my eye at least things look dramatically worse once we bake them. Normal mapped objects look flat as if there was no normal map applied to them at all. Here is a test scene lit with a single direction light set to realtime. The sphere and the terrain are using the same texture and normal map. Switching the light to baked lighting using Enlighten and Directional Mode looks like this. All the lighting variation is gone and it now looks flat. Surely this isn't how this is supposed to work? The normal maps are working to a degree. If you set the albedo to a white texture the variations in lighting due to the normals are visible, but they are much less pronounced than they are with realtime lighting. Does anyone have any idea what is going on here? Is this a bug? Am I doing something dumb that is causing this? I've tried messing with every conceivable setting over multiple versions of Unity from 5.4 to 2017.1 to no avail so at this point any suggestions would be greatly appreciated.
