I have been trying to get this room to look better( brigher..clean white )but stuck!

Because there are now windows I ended up putting lots of spherical lights and lumi panels.

any advice on how I should set this room up?

I am uploading my files and my settings.

sorrry im still trying to learn.

1. Turn OFF Physky (why You use this when You do not have windows?)
2. Everything is ok when I see render (I think You should setup TONEMAPING better)
3. try render with QMC (no interpolation for Gi) so shadow will be perfect

Light looks ok. You must tweak your materials to make it really look good. Make sure your materials follow 100% rule!

Thank you guys both for replying :)

I feel so much better now. relief...

I will try to render with QMC (I never done this before xP )

Oh, I have physky for some other parts of the building :)

Jure: as far as the material, Most of them has 90% diffuse with little bit of refletion, spec, glossy.

Any suggestions on what materials I should fix?

I am still working on this but please let me know.

Again thank you guys both.

You can try just basic setup, exponential from first tab of Kray.

100% rule requires you to keep the color*diffuse+reflection <100%. This prevents surface to bounce more light than it receives. The easiest thing to do this is by using nodes and subtract reflection value from diffuse value before it's pluged into diffuse output. Of course if your reflection = 0% then you can keep diffuse at 100%. When you use transparency or translucency the calculation gets a bit more complicated but you can read about it here.

it looks better but i don't like bright spots around your ceiling lights. What kind of light sources are you using?

what means QMC (no interpolation for Gi)?
what settings should I use?

Yes QMC = Cache irradiance OFF. Photons settings are the same you only need to check FG rays min/max setting. Other settings don't have any influence in QMC mode.

Thanks to Jure and Janusz Biela.

This job got killed but I enjoyed working this and learned alot from both of you guys.

I feel much better with kray now...(obviously still learning)

Thanks again!!
