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 ?

Maybe it's just my display-setting. :oops: 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 ?

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.

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 :D 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.
