About noise in general

[pixela]

Yes please. Thank you.
So we can see if there is any difference.

single glazing or double?

[pixela]

single is fine

Peter one more question:
Subpixel mapping is on or off?

[peterguthrie]

subpixel mapping off, clamp output off and dont affect colors off (i rarely do anything in post)

[peterguthrie]

here you go, glass has a very slight amount of fog. Didnt take much longer to render

[pixela]

Thanks Peter.
I see that there is not any noise problem regarding glass. Then there must be something in my scene triggerring the noise.

Peter, do you also try not to go above 200 for white colors?

[Morne]

235 for me,but recently been getting better results with 225

What value do you guys use as a black material?

[JohnVK]

I usually use anything between 1 and 4 for complete blacks, depending on the environment (lighting, placement of the object and the surrounding objects). I'm using LWF.

I would like to know the theory why it's better not to use for white anything over 200? I know that 255 with LC isn't recommended in vray manual but why even that low for white?

I think it is because Gamma corrections changes the curve of midtones.

[peterguthrie]

i think i normally use 235...

i guess it depends on your workflow, do people who use max gamma correction tick the 'affect color selectors' box?

For white I'm usually in about the same value zone, even though sometimes I need higher values (up to 250). I'm always kind of balancing them between the amount of burn and 'whiteness' in the render.

I have the 'affect color selector' box enabled, yes. Otherwise choosing the proper colors and having them match (to a degree) with the render is pretty much impossible. Within my workflow anyway.
