will it finish someday?

[daniel_nieto]

i put a scene on rendering pipeline....

Max num consect reject: 500
Strata width: 25
Max depth: 10000
BiDir supersamples: 4
BiDir on of course.

it has been rendering for about 15h now, but i can't see any changes from the 10h image, it's still noisy, with some fireflies, but my question is... if i let it render longer, some day will look real clean?. the igs weights ~68mb, it a 1400x1000...

i dont have any issue to let it render up to 80h or more... but i want to know if technically all the noise will be removed....

or i set up max num consec at a lower value like 200 and max depth too...?

[drBouvierLeduc]

Can we see ?

[oodmb]

maybe not all, but in general, the time it takes to get less noisy increases exponentiay. i recomend getting another computer and networking them together- then doing it for 80 hours anyway.

And a ray depth of 1,000 should be fine instead of 10,000.

[zsouthboy]

Don't bother screwing with raydepth, there is so little difference between 1000 and 10000, just leave it on 10000.

The noise that remains is exponentially harder to get rid of.

Consider the improvement from say, 1 hour of rendering, to 2 hours.
To see the same level of improvement again, you have to double the amount of time.

My guess would be 30 h before you see a difference from the 10h image.


Oh, and don't screw with strata_width. Leave it at default.

[daniel_nieto]

well thanks all, i would love to show you guys the work, but i want to present it, the way it's gonna be. besides the png is ~5mb!!! hehehe, i'm gonna do this... i'm letting it render a new version with depth~1000, and consect reject~200, and strata~20, over 20 hours and then i'll show you this, if this finish like it is now, i'll show you the noisy version, and then i'm gonna let it render 80 hours...

btw my pc is: AMD Athlon64 X2 Dual Core 5000+ 2.61GHz, 2GB RAM under Win XP 32bits. i just bought it the last week.

oh let me ask too: as my processor is dual core, when i render it uses both cores? or i have to networking them?

[oodmb]

set the infile to dual core. there is a setting in it. if you still have your old computer keep it and use it as a third slower core.

You can get rid of the fireflies by running it twice then recombining the images in GIMP or similar. The fireflies should appear in different places so recombining them with "darken only" as an option should get rid of them.

[Stur]

Let me guess : the noises remains mainly on specular materials, specially if there's SSS ?

At least with my renders, the diffuse and phong mats get clean rather soon, but the sss remains very noisy. That's why I asked, once, if it was possible to implement a region rendering feature that would take some object's name to render as a parameter. I got no answer so I suppose it's not possible

[daniel_nieto]

yess, but there arent either SSS nor CBC, in fact is not THAT noisy, but kind of... oh thanks IanC, i never came up with that idea!! i'm gonna try! thanks all!

[daniel_nieto]

yesss!!!!, it actually is going better, i rendered another version, i hadnt realized!!! the first scene i had was 1866x1333!!! i dont know why it jump to that size! i set it up at 1400x1000, anyway, it's way better now, its been rendering for about 22h, i havent turn off my pc since my last post here yesterday... now i ♥ it.... hehehe

Always a good idea is to denoise the image with software like NoiseNinja or something like that. It does wonders for my digital camera, and works great for Indigo as well
