Noise after 10 hours, I think I am doing something wrong

[ikifenix]

Well, I don't know what to say more, the black piano has a lot of noise after 10 hours of render, you guys have settings of material and render in the image. Any tips? Am I doing something wrong?

Thanks and sorry for my bad english.

Your entire scene has noise, it's just more visible on black.
The resolution you rendered in is 4282x2160 which is way above average (720 and 1080p).
So it will take a lot longer to clear out imo.

what color are the walls?

[ikifenix]

OK, I will try to render at 1080 and see what happens.

Walls and floor (for now, it is a wip) are 233,233,233 with 0,6 level in diffuse. BTW, all materials are at 0,6 lelvel.

You can try to lower the Max. ray depth to 10 or 12 and the number of path tracing samples to 8 or maybe 10, your scene have
a lot of light, not realy need to set high values.
You can also lower the Max. sample intensity to 10, sometimes, it can help to reduce noise.

Do you have glass in windows by any chance?

[Stan_But]

hdri? if yes - try corona sky
and better way to catch what is wrong would be share scene here

[ikifenix]

No glass in windows.

It is corona sky, sky model hosek&wilkie.

This is the result after all tweaks you told me and I added corona rectangle lights to windows (this is the reason color changes a bit from the first render), It has noise, but I think is admissible, what do you think?

Can you share the scene?

[ikifenix]

Can you share the scene?

Never!!  :P

Here it is, if you have an error locating 2 textures, don't worry, they were bluepints.

Edit: I added 2011 and 2014 max files to the zip.

resolution is less because there is no time to render, well, still not 10 hours will be in the original resolution!

[maru]

Maybe it's because of the lights placed in windows?

[Polymax]

The original scene had portals!

Holy shit, 6.000.000 rays/s, mine is only 2.000.000, I think the noise is more related to my computer speed than the render settings.

So, did you do any changes in settings? Just for know if my settings are ok.

Thanks everybody for the help and patience with me (and don't kill me fot my bad english).

changes:
1. Del the lights in the windows
2. set portals
3. set Mult.Sun to 0.1
4. Set pt to 32
5. Set depth to default (25) and MSI=20
6. Set max rec. HD cahe to 200
this all
and yes, upgrade yours hadrware!
