GI Problem

Hi all
I have attached screenshot of a room from my project. I have a room and it is lighted with a emissive material on the window. And the walls are standart material with no texture(just white albedo color). As u can see from screenshots, there are some strange things on the walls when I set the emissive number to 0(I want the room dark).
Is there anybody who have any idea?

 

Just a suggestion: room should look properly lighten without faking light entering it by using transparent emissive material on window.

 

I have tried it as well. However, this time some problem occur near windows and it looks bad. It is really hard to lighten such rooms.

 

Anyone from unity technologies to answer my question?

 

Thanks Jesper for help. I can send you a copy of project. How should I give you the project? I can clean some parts from project to reduce its size.

 

just submit a bug report and drop the case number here.

 

ok, I have submited the bug report with case number:653545

 

Answer from unity: They have managed to reproduce the issue, but they don't know when the solution will be available.
