Hi again!
I just noticed, that there is a problem with lense flares when I run my test map. In editor they work properly, for example when testing with prefab "cage light" or just creating lense flare, but in game they are not visible or just flash or flicker every now and then. Not sure when this started, have not payed attention to them until now when I started to think about light stuff... I'm using GTX960 with latest drivers. As always, any help is appreciated!
