Here is my Shisha-Scene
Rendered in 10 Minutes.
I avoided the glass Material this time due to the missing MLT.

very neat
you're images are always a tad too dark.
could this be because i made the interface of octane so dark ?
giving you a darker reference environment to tune exposure etc ?

Radiance

Maybe it's just my display-setting. I definitely have to do a colour-calibration.

i think it's due to the fact that octane's user interface is very dark, making it difficult to tune the image against.
i've noticed the same tendency in my renders, but i correct it by bumping up the intensity a bit in photoshop afterwards.
as a result, it looks ok, but once you see the image against a white background, it's too dark.

maybe i should add an option to allow people to change the colour of the border around the renderer ?

Here is an updated version in a higher resolution.
I rendered it with 12000 (!) Samples/pixel and adjusted the brightness this time.

That's better
What about render time for this one ?

[Isigrim]

I rendered a little more than an hour but that´s just due to the fact that there´s no MLT avaiable atm which causes some more artifacts for glass material. Once radiance implemented MLT this should be even faster.

[Sam]

So that mean you keeped it rendering for 1h only to reduce artifacts in glass ?

I just set it to 12000 samples per pixel, because i wanted to see if that makes much of a difference.
It didnt change very much after 3000 though. That means i could have left it render for just 20 minutes and it would have looked almost the same.
But i never rendered anything with 12000 samples per pixel before With CPU-Raytracers i just didn´t have the time to try things like that.
I am really looking forward to MLT since that will cut rendertimes even further.
