Aleks great image. Currently im trying to get the famous pool caustics.

Unless i fake them with texture caustic generator... i cant get them . I know its pathtracing/PMC and the rays are shot from the camera not from the emitters but i see it as kinda limiting...at least it should be a matter of time not just impossible as my experience is showing.

Thats good news.AleksBraz wrote:gpu is not magic but the ability to make much more with less
the time render you control, in two hours the picture would be approved by any customer I think, but I want to leave more time.
Aleks, can oyu turn off the caustics in Octane?
Also I saw that you have reflective walls insied the house (blury reflections) also maybe a BIG factor in your final time.
Could you tray one more interior with only diffusive walls, no reflections, and no caustics.
I dont mean to be pain in the a.s here.
What app did you use for modeling?
you can't turn off caustics in octane, cause it's like unbiased, and the caustic algorythm can't be turned off since it's the part of the equation - and anyway gpu programming has limitations it's more low level as I understood it, but with a high output rate..
glassy blurry stuff always increases render times on any render engine, interiors are still pretty slow, even with 4 gpus I have to cook stuff for over two hours, optimization is the key as always.. anyway when they kick out some new 16xfaster gpus, you'll get realtime, it's just really a matter of time now.. cpu+gpu can't really do that yet because of the hardware bottleneck
for simpler shots you get like a 10 second renders, realtime part is the updating of the scene, everytime you change something you can quickly see where it's going..

Oh well...I suppose Maxwell or Fryrender need at least 10 times more...
