Morning Calm
Some really outstanding renders folks. Nice nice nice!
Come on DAZ, waiting for those NVIDIA deals to be offered. GRRRRRRRRRRRR ;-)~
Some incredible renders in my absence y'all. I'm so far behind the ball. And Khory, My CPU only rendering is lacking just as bad, your not alone.
Is that all you did? Ctrl-click the Iray shader and "Ignore" maps? I need to go and look at some stuff again, I can't remember what one it was in that Iray Shaders folder (not the Silver or Aluminum ones, lol).http://www.daz3d.com/forums/viewreply/783723/
That looks good, and gives me hope for the collection of figures I have (that are not Daz Originals).
Greetings,
Very nice! I'm a sucker for calming images, these days...On a technical note, did you use the built-in Vignette setting, or postwork it? If you used the built-in, can you please share what setting you picked, as I've been wondering what it does, and at what strengths...
-- Morgan
Awesome DZ! You beat me to it! I was only in the thought process of how to do a proper cut. LOL Sheesh... now you have really hot cars and diamonds! You win... you get all the women. ;)Not necessarily...some women covet shoes above all else, and you made some great ones. There is hope yet!

Thank you, Morgan,
On this particular piece I used post work, as I wanted a more boxy vignette. Iray is more the standard circular/lens. But I played with the vignette before making that choice. Setting the vignette to 40 gave me a good, visible base to work from. Up to 180 was like looking through a tube or tunnel. One great tip is to use your Nividia setting on your view. The vignette is visible in the preview without having to actually render. :)
This used Top of the World's Environment Map, Iray shaders on the figure and clothes, and the sun from Top of the World replacing Iray's Sun.
So why did this render take less than 20 minutes to render on cpu only, when all my other renders have taken 2+ hours?
Mystery...
Is that light coming from the surface (sky-box), or is that TOTW light, actually emitting light? Good question.
Lights note that I can’t find; (Was I wrong!?)
Lights that only have “Lumen” controls are for Iray only. (And don’t work in 3delight).
Lights that only have “Intensity” control are for 3delight (And don’t work in Iray).
Lights that have both (Photometric Lights)... “Lumen” control is for Iray, and the “Intensity” control is for 3delight.
So just remember - “Lumen” control is for Iray, and the “Intensity” control is for 3delight.
Distant lights can replace the Sun/Sky light. This is also using the Environment Map as a light (thus the bluish lightened sun shadows).
The only postwork is sizing from 2000 pix to 1500 and the sig.
Greetings,
IIRC distant lights are 'converted', much the way textures are converted, with varying amounts of success. (Although apparently the more recent Iray, which may be this one, has a concept of a 'distant light' built in.) I presume the idea here is to avoid using the environment image's lighting, but unfortunately it made the background very flat.
As for render time, no idea. Were you using mesh domes (as opposed to the built-in environment), or anything like that, before?
-- Morgan
I distinctly remember cranking the spotlights up to 200% intensity, and NOTHING at all, pitch black. I'll look again, I never did try the dzDistantLight, as I was always inside a box, or sky-dome.

(EDIT)
Nada, nothing, zippo.
(EDIT2)
Decided to try the 'Menu' Spotlight as well. Again, Nothing at all. As for the two of them in 3delight, flash-burn anyone, lol.
(Edit)
And as suspected, nothing from the distant light. Either in a box, or simply non-functional in Iray.
I'll need to try that again inside TOTW... nope, nothing.

I bought Reality about a month ago, and was thinking about getting Octane too because it was such a pain waiting for the scene to transfer and start rendering every time I changed something, or finding a problem several hours into a render. I'm glad now that I waited :) But I did get a lot of practice doing lighting in Reality and it works the same way in Iray.
Couple of a green modified Chevy.
I'm fighting a bit of a problem with this one - as you can see, it is a tad bit fuzzy. This is after 2600+ iterations over 2 hours 16 minutes - and only 1% convergence. The light level is about what I want, but the speed isn't. :-)
All lighting is environmental - I'm using the overhead lights, the wall lights, the stair lights, and the skydome as emitters.
Would lowering the film speed/increasing the f-stop and increasing the light speed things up - or is this just going to take forever due to the size of the set and the lighting I'm using? (CPU only - I'm holding out on the high-end graphics card until DAZ gets the dealership lined up).

The background is an image on a iray dome, so yeah, it's flat. :lol:
No, I've not been using mesh domes, I have been doing mostly interior renders with mesh lights (Iray emmission shaders).
Ah, set the maps (bottom, north, east, west, south, top) in the 'Ambient' boxs (and diffuse), before converting it to Iray Emisive Shader. Then set the "Emission Color" to 6500k. (I have the Lumens at 10,000)
If the thing is giving you a lack of stuff below the 'floor' (checkerboard) on the sky-box, go to render tab, and turn the 'Draw Floor' off.
No lights, Camera headlamp is off. Just the Sky-box lighting things up. Now either turn up the Lumens on the sky-box surface, or crank up the Film Exposure in the render tab.
(EDIT)
Now this second one, I cranked the ISO up to ISO400.
HAH!!! Thanks barbult. Hmmmm.... maybe shoes with diamonds on them? :)

Thanks, Kat.
That was rendered before I read Sickleyield's great post on getting started, (http://sickleyield.deviantart.com/journal/Tutorial-Getting-Started-With-Iray-519725115). Nothing had the Iray Uber Base applied. I went back and applied the Iray Uber Base to everything and the Iray Optimized Genesis 2 Female MAT on the girl. I also applied the shader Water - Thin on the EyeReflection Cornea and Tear as recommended by DAZ_Spooky earlier today, (http://www.daz3d.com/forums/viewreply/783282/). I'll post both together, for comparison, in a separate post.
We've been told Iray likes lights, lots of lights. If all your "lights" are actually emitting objects, it might speed things up to add a couple of photometric lights to the scene. You can point them away from the subject and lower the luminosity to keep them from casting much light on the scene. See if that helps. I know adding a second photometric spot, pointed behind the subject so only a small amount touched her shoulders, really sped up the render. Anyway, it's worth a shot.
Yes, nothing more! ;-)

Edited to add image. They don't look like diamonds, but they look awesome in Iray.
As I mentioned to Kat, I revisited an image, which was one of my first Iray renders, and added the appropriate Iray shaders. For reference, I'm including the image I posted earlier, followed by the second image with the Iray shaders. I repositioned the scene in relation to the sun, but wasn't able to get all the shadow off the cyclorama. The angle of the shadows is a bit different, too.
The differences most evident to me are the overall skin, the hair and the eyes. The fact the second render is sharper may be due to rendering it much larger to begin with and have nothing to do with the shaders.

Yah - it was worth a shot. Unfortunately, it didn't help. I've got the lighting significantly brighter, even with the photometrics dialed way down, and after 1 hour 15 minutes and 1300 iterations - I'm at 0%. I think I'll put this aside for a bit and come back later; maybe something will come to mind. :-)
Iray, It's a grand new world,
To fill with your desires, hopes, sorrows, fears, and dreams.
Converted the Sky-box to an Iray emissive shader as described in my last posts, Photometric spotlight off to the left, and touched nothing else shader wise, yet. Still a WIP.
CPU (8 threads): 2487 iterations, 69.567s init, 7132.489s render

Yes, nothing more! ;-)Set the color thing “Emission Color” to 6500k, by default the light color is yellow. And that dial overrides the color box and map. Essentially tho, That's it.
After putting the maps in the 'Ambient' setting on the old shaders first. The Sky-box has six sides, each with it's own map.

Wow.
I'm rendering a close up of the girl above and I added two photometric lights to chase away the shadows on the cyclorama. It's at almost 48% in 35 minutes (cpu only) compared to the image above which was in the 60% range when it stopped after two hours.
It might have to do with the complexity of your image. If you're curious, you could set it to render overnight, with Max Samples set to 25,000, and the Max Time set to 28,800 (8 hours) or more. If it finishes before you get up, you can check the log file to see the render time and the number of iterations. I've read from several people, like Sickleyield, that you see the least amount of progress in the beginning and the end. With so many surfaces, it may take thousands of iterations just to reach 1%, but then move much faster.
But I know I hate to tie up my computer with long renders, especially when I have work to do. With no fancy video card, it impacts my mouse's ability to move across the page, among other lag issues. lol
I'm eager to see what deal DAZ works out with Nvidia. :)

I'm anxious to see what deal DAZ works out with Nvidia. :)There are a few other render settings, that I discovered (and Daz_Spooky brought up others), that may or may not effect render times.

(EDIT)
As for the GPU's, well, it will depend on IF my scenes can fit in the card or not. Imagine having the most powerful engine in the world, yet when you need it the most to pull that stump out, the engine can't get there to make the job easy.
That's what 4GB is like for me. I've been there, less then a year ago, and more recently I ran out at 16GB of ram with a scene. It's a kick pushing the tiny demos all over the place with all that horsepower, yet when you really need the boost the most, the Iray code will refuse to let the GPU do anything at all if it won't fit in the ram.
An extra 200watt electric bill, for a tool that I can't use all the time, I'm not entirely sold on the idea.
