...thanks, so that isn't is because I'm using pure CPU rendering.
...but 3 hrs 57 min is longer than 2 hrs 20 min, so how is Optix a speed improvement?
...apologies for the absence. I was in the process of moving ans thus offline for a couple days.
OK so removed the chandelier and just used a somewhat flat cylinder off camera for the ambient light and still just hung at 24.51% repeating the same convergence percentage over and over. This gives me a total of 8 mesh lights rather than nineteen. I need that fill light or parts of the scene are too dark even though it renders quicker (I thought someone said that Iray liked more light and if you have too much dark it slows down). This is really perplexing and a bit annoying as I have a deadline on this project (and I haven't even inserted the characters yet).
Some things I would try if you haven't already.
Use the Architectural Shader on the walls/floor/ceiling or a combination of the three to see which works---or not.
Try turning on the Architectural Sampler either with or without the above.
Try setting the Tone Mapping so that you can see into the shadows.
Try setting dome to Finite Box at the same size as the room and put an HDRI on it for ambient light and turn intensity and map settings down until you get the required light in the shadows. You might only have to bring the height setting down so that it is under the ceiling e.g. 5 is 5 meters, 3 is 3 meters etc.
This render uses FW Alfred HD and the included iray shaders, though I did lighten his skin. It was too dark with the blonde hair. The woman is just the base Genesis 2 female, with the Iray Uber Base applied. And a lot of modifications to make the skin look like that of an old woman. Used the emaciated morph along with Zevo's Aging Morphs and Vascularity. Mec4d's Unshaven 2 Iray hair shaders were applied to both figure's hair. There is a distant light behind them, and two spotlights on the left, one to highlight the wing, the other on the front of the two figures. The second light is set to disc, and is very large to create softer shadows.
I rendered the image at 3000 pixels wide and resized it to 2000 wide for the gallery. If you'd like to see the full size render, click on the image below to go to the gallery page.

Absolutely brilliant L'Adair. Good to see someone acutually render a scene rather than fluff endlessly around with shaders and lights and skin translucencies and settings . A breath of fresh air in the forum.
Southern France street life from the sixties. Somewhere at the Prom.des Anglais. DAZ 4.08 iRay render using G3F with some of my custom morphs. Lots of other G2 figures in the background.
Ashley: Yeah, seeing staring dolls sort of undercuts the sense of skin and detail, makes it hard to really appreciate the other work. If nothing else, I think people should come up with a simple expressive scene and just repeat that with tweaks. ;)
Anyhoo, despite having a sh*tastic week, managed to get my next comic page up today! Woo!

Hi there,
just started fiddling with hdr and skin shader....
HDR is tropical ruins from www.hdrlabs.com/sibl/archive.html.
Skin is based on http://toyen-art.deviantart.com/art/Daz-Studio-Iray-Skin-Shader-Settings-532976349
Anyone knows the difference between environment map and intensity sliders?
Thanks, Kay
Image removed for Nudity
Just my opinion of course, but for all of the twiddling with skin settings, I have yet to see a render posted here with skin that looked appreciably better than the Iray shader provided with G3F/V7 and associated vendor products etc or the default G2F Iray skin shader.
Thank you, Ashley.
I really didn't need to let it run the 3hrs,, I just got a bit busy around the house :)
The average number of iterations per minute is what I was looking at, had I been watching it a bit closer I could have gotten it stopped in the same time as the 2hour one, but I'm sure I would have still gotten the same results.
an average of 3 iterations per minute with out optix, and an average of 3.6 with optix.
a gain of .6 isn't much, and it may vary depending on the render.The good news is, it does work for CPU only mode, it's just not giving huge improvements.
...actually I've changed the view angle so the HDRI is no longer necessary. Again it wasn't the HDRI as I one of the first tests I ran was with the Dome turned off and it still hung at that percentage.
As I understand the Architectural sampler slows the process down even more which is why I haven't used it.

Ikyoto that is adorable.
I've been working carefully to reduce the render load of stuff for my web comic so that my workflow isn't really untenable. I actually have the next page done, which puts me a full week ahead!
Sooo of course I go nuts with SSS and am thinking up a busy scene with things like...
..oooh flutterbyasaur. Leela likes.
Posted this in another thread (the vendors one) but thought I'd put here too as I think the skin came out quite nicely in iRay
Those eyes are amazing, Apothis... that's one of the hardest elements to get right!
Thankyou :) Thats about 12 mins in iRay :)
I absolutely LOVE this little guy. :) Well done Ikyoto.
Excellent! What is the texture by the way. What store sold it?
Thankyou, the model and texture is http://www.daz3d.com/ej-atsuko-for-genesis-3-female-s
I actually have that one but have yet to use it. Thanks!
It is an excellent render; I also have that and have yet to achieve such outstanding results. :)
Nicstt: Yeah, with some of the really good artists, I feel like one of those 'nailed it' memes...

LOL yup
I am working on converting the Chroft Apartment - Open Plan Living over to Iray.
http://www.daz3d.com/chroft-apartment-open-plan-living
These are un-retouched renders with no additional props added at this time. I am using all of the original diffuse maps, bump maps, and spec maps from the original. I trying to stay away from just using the default "Iray Uber Base" whenever I can but I am mostly using various Iray shaders that I purchased here on DAZ and then doing some tweaking of those shaders as needed.
Even now that I look at it, I see that the floor needs some roughness because it is too reflective. I also need to change the HDRI lighting so it doesn't look like the apartment is right on the beach but overall I am happy with how it converted. The set has lots of bump and spec maps which really help out. I am finding that older sets just look plain and flat if they only have a diffuse map. I move the bump map to be a displacement map for Iray since Iray seems to be about accurate simulation and not faking it with bump maps.
I have a few other conversions done now and I am thinking about doing Lava Planet from Stonemason next. I think having the lava textures set to actually light the scene should look really nice. This has really been about me learning how to use Iray and I think I learn more from working on these sets than I do with figure or clothing conversion.
... it doesn't really rate compared to that amazing apartment, but here's some experimenting with Carrara metaballs imported into Daz Studio...
Ivo Shandor, very nice job on the lighting. That is what impressed me the most. The metals and cloth look very nice, too. I agree that a less shiny floor will add aditional realism.
