Dark room when disabling artificial light

[vsilver17]

Hello everybody! My problem is that when i disable artificial light the sunlight is not enough and the room is almost totally dark. The strange thing is that the room is south exposed and i set 10 July at 13:00 so I think it should be totally enlightened.
Can someone help me find a solution if there is any?

You should try this: put 3 or 4 white light sources, size 0,6 - 0,8m, power 10-20%, elevate them a half of your room height, turn off ceilling light. Set 9-10am and let the sun through window. Good luck.
If you still have no idea, send me your sh3d file, I will help you.
