I started a project with 2 levels, but central room open to second floor (no ceiling on first floor and no floor on second floor; Think of a walkway across a room). But when I did adv. renders, the lighting results differed a lot depending if camera on first or second floor.
I tried balancing lighting with lights on both levels but camera seems to ignore lights on other floor location.
I finally gave it up for speed (adv quality not really needed) but wondering if that is an issue and others have seen the problem and maybe know a "fix".....or it is my own design construction problem? or a "bug" in TFP or its "mother program. I may experiment with a simple two story design when I find time....but previous experience by others may be helpful?
