Hello;
Can anybody help me to solve for noises.? I am using sketchup indigo. I have only 2 light sources; sun and sky. If I add some other lights İt is seen on the scence and I do not want it.
Thanks in advance.

Hmm, looks odd. Do you use arch glass for your glass panel? What rendering mode? Have you tried using exit portals for those windows?

Well, that could be an acceptable noise level depending on how long it's been rendering. With CPU rendering, interiors can take hours depending on the scene, resolution and CPU.
Exit portals:

Depending on what lighting you use, exit portals don't always give favourable results currently.

lighten an room through glass & curtain material is render intensive, so noise will take time to vanish.
You can make sure to disable glass & curtain meshes from windows that are not in camera focus to allow faster rendering.
Also if you are using some texture for the curtain with a BW mask to control solid & transparent holes on a microscopic level, you can try to enable "step blend" for that texture. That should give some slightly faster rendering too...

Check your white wall material too - make sure its not rgb 255,255,255. Thats pure white and will extend render times a lot which manifests as a lot of noise after a long time. Make sure your white values are around 205,205,205 gives acceptable whites, without dragging the render process out for a week.

Actually white paint has albedo about 80%, so setting RGB to about .91 is still ok as RGB values are gamma-corrected.
