I am having problems with this technique. DFAO is not showing up at all, distance field shadows are working only in the editor and go away in play mode. All distance fields are generated correctly and I can see DFAO and global distance fields for the whole scene in buffer visualization. I have Nvidia 840 that supports dx11 and intel hd graphics(that should be disabled). Engine setting are on cinematic. Right now I feel like they would be broken in deferred rendering as well.
Update: Works fine in deferred rendering, but occlusion max distance is not exposed to bp for some reason.
