Room have 3 window and i placed Bounce Cards with spot light behind all of them. After building it became really dark and looks like my setup don’t work
so, i’ve done some testings and found out that as soon as i add some props it becomes dark as hell. Even after removing those props after building it remains dark
I hope Epic adds real area lights soon for arch viz and cinematics! I miss them especially for latter, in offline rendering they are used all the time. Maybe the Enterprise team can have a look at the implementation.
