Hi,
There has without a doubt never been so much fun to render as it is now, I really enjoy testing out this renderer.
These are just some test I`ve done while trying to learn this wonderfull piece of software, many more to come...
Can`t wait to see what the future brings
Best regards
Ola

So true the worst ( and the best ) of this is that now im actually more addicted to octane then playing games

nice renders love the architect one and the sharpness of the scalpels

My thoughts exactly! Octane has turned rendering from a tedious chore into a VR-like experience, more realistic looking than any game

I specially looove the urban model one!
Just add a little bevel on the table edge and the result will be better.

Hey I just noticed that the architecture illustration I did for the competition has made it to the front page

,
I`m so honoured to be there considering all those great artwork that was submitted.
@pixym
The table never got finished for the competition, it`s just a "dummy" for the table I`m working on,
but you are right I should have used 2 seconds to bevel those edges.
Hopefully I`ll have it finished in a couple of days, and of course I`ll render it in Octane.
I have noticed while doing some test that interior renders with only small window openings takes a really long time to render clean,
the architecture piece had to render for almost 10 hours before it got clean on a GTX 285 card at 1600*900 resolution.
Hopefully this will change in the future.
But this is the first time I`ve ever tried a unbiased render so I haven`t got anything to compare the speed to.
take care and have a nice weekend everybody..

Thank you guy, Have a nice WE too.
Regarding Interior scene that take long time to be clean: Perhaps radiance will implement a Lightportail feature that will force the light rays to go insideā¦

Interior rendering is long because there's no MLT
Metropolis light transport is better for interiors
Don't worry its ranked 1 on the TODO list

Re rendered one of my old scenes in Octane, some noise and fireflies has been removed in photoshop,
other than that it is a pure octane image.
I know the mirror looks strange but i forgot to adjust the material so lets just say it`s a foggy mirror
What kind of speed /noise improvement can we expect when MLT is implemented? Does anybody have some
experience from other unbiased render engine when it comes to that...

That's a nice bathroom
The floor is a little bit wet (no pun intended) maybe reduce the reflective ammount. You could use glossy materials with 0.1 reflective for the wood drawers they look like yummy chocolate to me
The more glossy materials the better it would look, try glossy material with 0 in reflective ammount and 250 roughness for the walls... That's what I use in Azuma house it look more realistic.
Except if its very rough walls and you want that effect
Ill raise the camera ISO a little bit also (+50 or +100) and maybe the gamma from 1 to 1.25 or even 1.5 depending on the camera reponse you are using
For example "Ektachrome 64TCD" doesn't look good with a gamma of 1 because everything is over-contrasted. But if you raise the gamma to 1.5 its very nice. I used it in the Azuma house also.
Also don't put too much vignetting, architecture photohgraphers try to avoid and correct the vignette effect a lot
Oh and try to get less "orange" whites, its not a big problem if you look only this render. But in a gallery of renders it would look very orange
Your render is very nice, keep doing more renders of that scene its a good scene for sure
MLT gonna improve noise when you have specular materials I think
But it could also help for interiors when its only lit by bounces im not sure

Thanks for the comments Sam.
I do agree that the floor has way to much reflection and there for looks wet.
The furniture already has some reflection but it might be to blurry, will try to raise the roughness some more and also try with some reflection on the walls.
The reason for the orange look was that I was going for a warm morning light setup, it might be to orange but I kinda like the look of it:-)
There is no vignette turned on in the picture so the effect you see comes down to the materials and the lighting.
But I don`t know if I`ll render the whole scene again as it is before MLT is implemented, at the moment it takes to long to make this kind of image somewhat clean.
This render did cook for 8 hours before it reached 32000 samples and it still contains a lot of noise. (1440*900 GTX 285)
I really like to play with this render engine but I`ve not seen those minutes instead of hours render times yet, maybe I`m just trying out the wrong scenes
