Sometimes while baking Baked GI, I notice objects in areas with only indirect light turn completely black. This behaviour goes mostly away when using final gather, but not always with the best results. My bake settings have ambient light from a procedural skybox. (though the result is the same with just a flat color). One directional light, Only baked GI, resolution of 10, indirect on 1. Non Directional lightmaps. Example: By adding a pointlight, I can bake direct light to the dark surface. But still no indirect light. The black wall segments are the same as the lit ones around them.
