This is the sky light.

This is the sky light + key light without GI.

This is the GI with photon intensity 100

This is the GI with photon intensity 100 + FG
[color=white]It is very weird [/color]that plus FG does not any help on my image but make the whole room so dark

[size=3][color=white]This is the GI with photon intensity 12000 + FG.
I dont know why the blue comes out from the wall and the cabinet and how to figure it out.
Help needed. Thanks!
