Just a WIP... my first official work with Octane

This is the first project I want to use Octane (I am a Maxwell user) and I am really happy with the results of Direct Light, especially when I choose Diffuse for GI mode... The reason I bought Octane, is exactly this... The combination of the biased and the biased renderer, with GPU speed.
But, I left my PC rendering in PMC for 7h08min and all I got was 2985/15000 samples, at 3000X2250 and the result is not good.
I expected something better... I know that night shots are much more difficult to clear...

This is a model from Revit, exported to FBX... Max Design 2012 GEFORCE 550 Ti Driver ver 310.90

So, what do you think about the result? Don't critisize the quality of the materials etc... just the result for the rendering time...

Do you think it would be much faster to use octane lights (IES) instead of geometry lights?
The geometry of the light sources is quite simple.

Thank you in advance for any comments.
Great work, Octane Team!

550 Ti isn't exactly a fast card.
Geting a faster GPU would speed up your times alot.

Is it me or your image is slightly out of focus?

Yes, I know... the obvious answer... :) but these are my first steps in GPU rendering... and with the economic crisis in Greece, there is not much work to do... so I will wait...
On the other hand, with 3 i7 network, I can go on using Maxwell...

What do you think about my second question? IES lights will make a big difference?

It's not necessarily how many samples Octane renders per hour, but the result of those samples. If you have lots of glass in the scene - you can adjust the kernel -> direct light importance so that more time is spent on "behind" the glass renders. Also, adding a non-zero "index" to a specular material seems to substantially increase render time. So in summary, you can increase render speed via material and kernel settings - the Octane manual describes the kernel settings well and is a good place to start.

Thank you... I already started reading the manual but there is nothing like making tests and talking to other users..
