What can Arion do in 10 minutes?

There are 3 differences between 2 scenes,

1. Sun light
2. Texture of backplane of chairs
3. Texture of floor.

Exactly and the sunlight adds most of the warm tone as it scatters more light off the wood material.
However the noise distribution is way more equally in octane, for some reason Arion tends to have bigger splotches specially on the wall as i hardly belive they would put a bumpmap on it since it already IS noisy (On the other hand its a great excuse for the developer to explain the noise, HA Radiance i know why you want to add bumpmaps XD), making the overall visual experience more "biased".

Still a rather depressing image, not much of a support for kids to got to school XD

That first one does'nt work, the MTL file is missing...
The second one (blend file) loads fine into blender, with OBJ export,
and opens up with no issues in octane...

I've done a rendering as a comparison.
The GTX285 used for the arion image has 1062 GFLOPS.
My Card has 572 GFLOPS,
so the equivalent on my GPU in rendertime is ~18,5 minutes.
if fryrender actually uses the CPU too it's unfair as i'm not using the CPU, only my GPU.
However a quad core CPU has only ~50 GFLOPS so i don't think you'd actually notice a difference in the image noiselevel with it.

Attached image cooked for 18,5 minutes with pathtracing.

Also, if you examine the fryrender image, it's postprocessed with noise reduction,
you can see it clearly under the window frames (in the dark areas on the right, between the floor and the window frames),
and on the walls, there's a blotchy noise which is the result of a wavelet noise reduction filter.

My image does'nt have noise reduction, it's a pure render.

I also did'nt have the time to set up all the materials etc...
It's a straight import from the blend file, with a few quick tweaks to make the floor and desks a bit less glossy and the chair metal look aluminium like.

Curious about your settings used for this render.

Default settings for pathtracing...

Hi radiance
I renderd this scene in higher resolution, render time is 15min is very good time! Arion use more CPU cores and nvidia 285, octan only 1 CPU core and GPU 260
very nice

Janaro666, what is causing the "shadow" lines in the lower right corner of your image?
