A few shots from the latest work, plus five panoramas in the rar file.

Octane for 3ds Max (DL kernel, AO mode), Photoshop.























Link to the panoramas (7K resolution), html works fine with Firefox and IE, but not with Chrome

Really nice shots although they are rendered with DL/AO kernel
The only thing I don't like is the sterile, cold look of the interiors. Some evening sunlight would warm them up a bit

Looking really great, since its DL/AO i guess it wasn't been rendered long either ? Can you share screen grab of your DL/AO settings ? Did you used HDRI BG or Sky environment ?

Thanks

DL settings:



Render time: one hour for the 5K image, three for the 10K panorama.
The sampling rate for all small lights - 100 000. It seems little crazy, but it works

Thanks for screengrabs i really appreciate.

I never get that nice ceiling with DL/AO, its always ether too bright to be realistic or blueish from SKY or too dark if i set AO distance too big . What happens if you switch Kernel to PT ? Do materials still work/look good ?

Thanks and sorry for so many questions .

Should add dispersion with ~0.01 for mini-diamonds (lights).

Should change kernel to PT or PMC to get true photorealism because your 2x GTX 780Ti SLi are very fast.

Don't get me wrong. Render time was a priority.

Try to render 10K image with PT or PMC kernel, when you have a dozen small ceiling lights, several inside the crystal chandeliers, without noise, in a finite time

When you use DL kernel, you can work in real time, rendering isn't really physically correct, but close enough for me, and is fast as hell.

The visual difference between DL and PT kernel wasn't so spectacular. But noise levels and rendering times, was.

To be honest, I found tips for good and believable looking renders with DL/AO in this thread:

Thanks for the solution Paquito

Exterior walls and windows - single sided with normals facing inside. So that you can illuminate the entire scene by a single color texture environment, (white color, 0.3 power), you can of course use HDRI image. Windows material - Black Body Emission - 12 000 Kelvin. Camera with rather high exposure - from 3.0 to 6.0, highlight compensation 0.35 to 0.45, gamma 0.9, custom white balance.

Interesting tips, thanks and i'll check Paquitos topic more then.

So you are saying that if you had double sided walls (thickness) then it wouldn't work that good ? I often needed to render flythoughs so buildings need to be modeled form outside also. I guess i could porbably split it in 2 layers and have exterior walls as separate entity in that case.

You can download PAQUITO scene from his thread and test it.

really good results using Direct! I'm not one to ever work with the direct kernel but i think these are pretty great. i'd randomize the tiling in the crocodile skin bathroom tiles a little bit so you don't see the repeating. In an image that high of quality it really stands out, so keep that in mind for future renders.
