strange noise

Look at this render (no adjusting, just crop)
at higher sl begin tiles look noisy, glass is more clear, but some walls and floor look more noisy. But that noise look strange to me. Look like not same than normal Maxwell noise in the early stage of rendering. I know this is most problematic scene for Maxwel in this stage. Scene is lit by sun and sky hrough small windows. Only weak emitts are in the kitchen... But anyway, what do you think?
Cheers
Edit: I forgot: render time 194 hours...

spekoun, your light looks strange, and your materials look strange, too bright. Have you read that thread about material reflectance?
Are you using Max? What is your system scale setting in Max (not your display scale setting) and what is the Maxwell conversion nr?

No, no Mihai. I read everything you noticed. My mat look strange??

I thing my floor is fine. Self made in phoshop, seamless and hires... Same with tiles. In PS looked fine. I checked brightnes of my textures too, to not have brighness over 85%... Anyway, why it does look fine at lower sl???
Adam: Yes, I will let it render until Maxwell final release!!
Cheers

Well better said your shadows look strange, too washed out. Are you sure your scene scale conversion is correct?
The noise you are starting to see looks like artifacts from caustics from the glass. I don't know if that's a bug or caused by wrong settings...

Another example. Look at ceiling:
Is not it some caustics, that will clear up at Christmas???

I use cm in Cinema and multiplier is set on 0.01 I am sure it correct...
Insted of these strange things, these renderings I like much more then i am able to do with C4D...

194 hours ?? semms too much for me... well you didnt say the actual size of the image, but i have rendered interior images 2000 pixels wide with almost 2 million polygons 20 lights in just 9 hours SL 14 or something like that, mmm my opinion is that you really need more ram ...
