yup thank you for replying
Yes i turned anti-alising in the render globals
probably there is an option to improve antialiasing and i don't know it
about the ceiling, ok i will lower it more lol and any suggestion to make it look better? or did you mean the ceiling lamp?
and yes i am using two ambien lights
they are not too intense, probably they are too close?
i don't know exactly how to place them
one is outside the "room" close to the window
the other one is in the center of the room, just below the ceiling lamp, could that be the problem for the edges??
thank you for helping
