Strange Render Problem

Hi volks,
I am trying to render a scene of a simple Corridor. Till now i have never had such problems.
The settings are high and i still don’t know from where it comes.

Here is the image. I have 4 V-ray lights. Rendered with V-ray Camera.

Here are the settings:

Please can someone suppose why it looks so baaaad ???

What is your primary GI engine?

Best regards,

Irradiance Map. And the secondary is LC…

In that case you will need better settings for the irradiance map, -4/-2 is too low in this case.

Best regards,
Vlado

Thanx Vlado - I will post the rezult with the better settings.
