Oclusion culling working wrong with shadows from directional light

Hi, I'm Kuba working on www.superhotgame.com. Since we switched to Unity 5 I simply cannot get occlusion culling to work as intended with realtime shadows turned on. Wrongly occuded blocks are marked as both Ocludees and Occluders, just like we had this in Unity 4 where everything have been working and occluded properly. Is it a known issue or should I file a bug report?

Gif from latest version of engine (5.1.1f1), right edge is the edge of viewport:

 

Yeah I've been having this problem too, would be super happy with a fix as the optimization it brings is massive.

 

It's seem to be weird. Waiting UT for the answer.

 

I submitted a bug report and it got closed as 'not an bug'.

I confirm that it fixed our issues on most of the levels, sometimes I have to go with 'Smallest Occluder' value down to 0.5 but it works.
I find it strange that we didn't have this problem in Unity 4.6 (we were baking occlusion on default settings and it was working just fine), but maybe our level's geometry changed in meantime, I don't really know.
However tweaking settings fixes everything and it is enough for me.

 

Awesome! this works for me fine. Glad it worked for you too.
