      I tried your sketchup file, and I agree that the render takes abnormally too much time.

      I found this : one reason that your render is incredibly long is because one or several materials.
      I delete all your materials and the render was very fast.

      But i don't know which material makes you trouble 😕

      EDIT : i do this override material render with your settings (except for the output settings)

          After defaulting all materials and render settings, it rendered in a couple of minutes. I reloaded the nightmare.visopt and fixed the IR and LC settings as they were set to render from file, and it rendered fine with the settings too. So in conclusion, there is a funky material, probably something from an older version of VR in there. Unfortunately, this legacy stuff needs to be reset and start from fresh.

          Do you mean that there could be a problem when is used material from older version of SU/Vray? This could happend - because this is updated old scene.. So I should delete all materials and create them again?

            Thanks guys,
            Yesterday I have tried to change lights & materials setup, uncheck low thread priority according to your answers and render it again (1600x1200). From reflection materials I removed any bump maps. Aqua blue material with some weird characters "×óãóíèé1" was removed and replaced with standard glass.

            All materials without any reflections was rendered fast as usually, lampshades, bed & chair and floor slower, but with possible speed. The rest of the render - bathroom, TV screen where glass wall reflected, wooden shelve under TV and of course glass wall spent over 20 hours and I am on 90%...
            Packed scene with updated materials: http://leteckaposta.cz/145119615
            Maybe I am wrong but there is not any special material setting used.. 😞
            For example floor material and shelve material should be similar - only different texture and amount of reflections.

              Absolutely. There have been massive improvements to materials since 1.49 version. Any old files might cause issues in 2.0

              The glass panels with refraction glossiness will take some time to render depending on the subdivs, but I didn't see settings that were all that high on it. I think there is a buggy material in there that needs to be hunted down or just start from scratch.

              What are you machine specs? It looks like you have 2 render buckets. That could be the issue too. A dual core processor would take a long time to render any file you throw at it.

                Ok, I´ll try to remove all materials and start from the schratch..

                  It might help to use the new V-Ray Material that was made available in version 2.0.

                    Why was it introduced, btw? What are the benefits of it?

                    This guy was having trouble with it: http://forums.sketchup.com/t/bump-slot-in-the-vray-material/4382
                    But I'd like to know what are the pros compared to the "standard" material. Is it faster?

                      It's the V-Ray Material from 3D Studio Max. It is a bit more optimized, compact, and I only hear good things from our artists who use it. If you want to use any of the optional maps that we have in our standard material, you can use the VRayBRDF which is just the V-Ray Material embedded in the Standard material as a layer. It's a little confusing, but that's the workflow at the moment.

                        Yeah it is 😄

                        I actually always prefered the "standard" VrayMtl in VfS over the VrayMtl in Vf3Dsmax. I use both, and found the layering in VfS to be much more easy to work with.
                        For instance, the fact that we don't need to mess with the refraction to make a simple glass material (In max, we need to make it fully refractive with a refractive IOR of 1. So much for simplicity)
                        And with the layering we can stack multiple diffuses, or reflections, etc.

                        But maybe I'm missing something? I'd love to hear other people's opinion on this. Like Ted?

                          Thanks to you all - I removed all materials and start from a beginning.
                          Today I finally rendered the scene in requested resolution 1600x1200 - in 5 hours.
