Can Unity 5.5 load Occlusion Culling additively?
Since the release of 5.5 Unity is supposedly supporting multi-scene occlusion culling. Does it mean it is possible to use LoadLevelAdditiveAsync to load level with baked occlusion data? I tried baking for all scenes that are being streamed additively in my project, but occlusion culling doesn't seem to work that way at all.

Here is what the scene looks like when loaded in Single mode:
