Too much noise on final render

[paulostorch]

Hey guys,
Im facing a lot of noise in my final render, and i can't understand how to solve it. Im attaching a crop of my render (it has 2500px by 2500px uncropped) with some red dotted retangles for you to see what im talking. Im also attaching the parameters that were used to render. I used a Corona Sun and a Portal (with CoronaPortalMtl) to light my scene.

Can you help me? Thanks in advance.

What image filter (System Tab) do you use?

What image filter (System Tab) do you use?

Image Filter: Tent
Width: 2,0

That's not noise, that's lack of antialiasing. You crancked Gi vs AA to unreasonable value and Corona throws too much samples to GI, leaving too few for AA. Just reset render settings and render until image is clean from noise.

Could be a wrong DOF settings at your camera...too...

Gi vs AA = 60?!!!
LSM= 4.0?

My friend, listen romullus suggestions.
Reset the file and use the default settings.
