Need Help About Noise

[awaismalik]

Hi

Its clear your lights are unbalanced.

Probably your middle curtain has some really bad settings. Try opening the window and render the same image with owerride material et to 160 white~

Test how will that work, if it will help try unhiding your curtain and exclude it in owerride then check if noise is back. If it is its you need to look at forum for curtains topic that was started already.

Thank you for your reply i will render again

It's probably some basic mistake like solid glass in the window hole or no portals or strange curtain settings. Please read:

And maybe also wrong gamma.

HOLY CRAP!... thats some serious noise.
Check gamma, and double check glass material from windows and opening.
Seriously.. never seen that much noise here in the forum.

What did you put as lights?

i think wall shader is the problem in your scene , you have a dark wall and also high light intensity . render your scene with override material (grey) and setup your light amount . if the problem was fixed then you can use a raiswitch material for your wall with a bright material in gi slot.

what is your curtain shader ? (did you use translucence for that ?)
