...my system, while more than adequate is nowhere near "top end" compared to specs of specs I've seen posted on the forums here:
2.8 GHz i7, 12 GB memory, Nvidia GTX 460.
Iray is completing renders, of a very "heavy" test scene in the way of texture maps and polys, in just over 2 hours at 1,200 x 900. I am not using any other lights save for the Iray "Sun" and "Sky".
How much memory does your system have? My test scene has three figures, a lot of reflection, and transparency maps which take up just over 8 GB during the process.
Just wondering if there's a way to brighten the text in the surfaces tab, or are they faded out because you can't use them?
I cant see them on my monitor, so I have to hover over the selection, click, hover, until they change to orange. I can alter the colour in the custom section but it alters other defaults as well as the text.
Cheers.
Quick question: Are you applying the iray ubershader to everything in your scene? Generally I would think everything would need to have iray shaders to be translated and render better. Also AoA lights don't work with Iray, You would use the photometric lights, HDR, and emission surfaces only, AoA lights are for a different render engine entirely.
No ubershader. Just a blank scene.

I only have 16gb of memory and I'm on Mac OS Yosemite (10.10.2)
As a rule of thumb, the test I did with Cadet Brianne took 39 seconds with 3Delight and almost 10 minutes with Iray. That's a huge difference. And using the GPU on Iray makes Mac OS 10 unstable on a MacBook Pro with a nVidia 650M GPU.
Yeah... therein lies a big part of the problem then. Iray seems to be designed for outdoor scenes. While indoor scenes might be possible, it would take a lot of time tweaking to get what I can get much quicker and render much faster with 3Delight.
Don't get me wrong, I'm glad I have the Iray option, but it appears to not be something that I will use.
That's just not true. Frankly, I think it's easier to do indoor scenes.
But it takes time to adjust to how things work, and if you don't have the time or energy to see if it will prove worthwhile for you, that's your prerogative.
From the earlier posts, it seemed to take more time. Although I do like that you can light scenes with objects.
Still, the render times are just too long for what I do. While I could spend time adjusting and tweaking the light sources to get a satisfactory result, that would remove time away from other aspects of the project. While I am a hobbyist, I don't have unlimited time like yourself. I still have to work, take care of the kids and the house. So what time I do spend I'd like to dedicate to something that will produce results in a reasonable time frame.
For those like yourself that can take advantage of it, I'm thrilled. I'll be the first one to 'ooo' and 'aaahhh' over your work. Sadly, until I can invest in a more powerful computer, I'll have to stick with what I can reasonably expect to get results from.
It's an investment, like learning anything. Personally, I had my doubts at first, but now... frankly, it's _easier_ to light a scene in Iray than in 3Delight.
With Iray, I made a scene with a fireplace and a candle. Lighting it: make fire object (mage tower) an emitting object, set it to a cool temp like 2500 or so (I forget what I used, but it looked yellowish). Make candle, look up light bulb temperature... hey, candles are listed as 1900. Set candle flame emitter to that temperature.
Increase luminance on both appropriately. Go to the render settings (tone control), put the main window on NVIDIA Iray (so I can see an accurate preview) and increase exposure until I start seeing the scene I want.
Done.
In 3delight, I'd be fiddling with spotlights, weird gels, maybe uberenvironment and tweaking a bunch of stuff. Or I'd use uberarealight to turn the same objects into lights. But then I'd probably still need uberenvironment to get the effect of light reflecting off countless surfaces and filling the room. Also, uberarealights are almost as slow as Iray.
And as for time, don't assume. I am a stay at home dad with two 6 year olds, one of which is only in half day kindergarten. And I'm responsible for cleaning and housework.
So I have MAYBE 2 hours a day free. Kinda.
Free time?
I'm retired and still have very little of that
Time is an illusion. Free time doubly so.

The text fields in the render tab are still annoying as all bleep, and what about the displacement maps on a primitive cylinder, hmmm.
I break to many things to have free time, lol.
The iglitches pointed out are not a joke by the way, fix them please.That image name editing but first showed up in 4.7. I bug reported it and it was also acknowledged in the forum. CS says it should be fixed in the next release. I don't know if that is in the next Beta or next production release. It is one big PITA though until then.
Unless you went into the render settings and changed the Max Time, your render should have ended in two hours, if not sooner.
Several of us on PCs are dealing with the render engine hanging. When that happens, the timer continues to count but nothing else is working. When we attempt to cancel, the program stops responding completely. I believe that is what happened to this render. Were you able to cancel normally and continue?
Your next post shows you were able to render the single figure in Iray. Have you tried anything in between?
I do not have a video card and do all my renders with the CPU, and I have one scene I did in 4.7 that hangs 4.8 every time I try to render in Iray, no matter how I try to optimize the objects in the scene.
Also, if you don't convert the shaders to Iray beforehand, the program has to do it on the fly. It is conceivable one of the objects being converted caused a problem at render time.
And finally, don't forget this is a beta, both of DAZ Studio and Iray, and it's been out for a relatively short time. By the time 4.8 is released, they should both be stable and much more consistent.

So, 24h 47m and less than 1s.
At least that's what I'm getting from it.
Is LIE super buggy for anyone else? Currently for me if I try to use it while the render engine is set as Iray I get instant crashes. As soon as I set the render engine to anything else it works fine, so everything's still workable, but it is a hell of a pita.
2 more questions about Iray:
1) I am missing a Fresnel parameter in Iray Uber Shader. Are there any plan to bring this layer effect to the base shader?
2) When a render finish are there some method to get some statistics beyond the render time, as sample value, convergence value, etc? Is it possible to create a script to gather these information?
Fresnel is one of the Top coat options I believe. It's in one of the drop downs (running a render so I can't check which one)

You must set top coat value to greater than zero, then the options appear with the pull down for Fresnel.

I think many are rendering with the gamma set to 2.2 when it should really be set to 1. It makes a world of difference to the look of the image.
It's certainly your prerogative, but I think it leads to poor lighting practises which don't actually use the light settings properly (iray being physically based), and has also led to comments about images looking flat when there really is nothing at all wrong with the iray renderer. Still, whatever floats your boat, as they say, and I'll stick to gamma 1 ;)

On the left is the NoGC 3delight render color cube, The render in progress is me still trying things out. With crush blacks at 0.2, the bottom end of that scale is pitch black, and it shouldn't be.
(edit)
I think your on to something, as all the mats we are messing with, are made for 3delight at the default Gama-off settings. Ignore Wachiwi-gone-red. Look at the background, the rocks, the shadow. Much better looking with Gama 1.0, and ISO doubled to compensate.

Thank you both! How can I miss that... I will take some coffee.

I think the report is just unreliable if the render crosses from one day to the next.

During the witching hour all clocks are going wrong ... ;)

This weekend I did a render that took 47 minutes, but it also showed '1 day, 47 minutes'. I think the day gets added somewhere along 40 minutes...
Peter.
If I had 2 hours a day, that would be awesome. I have that in maybe a week. If lucky. Sometimes I go a few weeks in-between. It sucks, but what can you do.
While I understand your comments, it doesn't take into account renders. Rendering time is on the order of 100x longer on some renders. Even my simplest renders are taking around 10 minutes. While they look great, I always seem to find something I missed after the render is complete no matter how much I try to catch everything. Perhaps it's my OCD, but I still tweak the scene. I've worked out my lighting systems pretty well on 3Delight and have presets I use with very little tweaking required. I can do a quick render in 3Delight and move and test. The Aux Window helps with that now, but since it's not showing the exact same thing as Iray lighting-wise, it will still take a render to see what's happening. Even waiting the 3+ minutes to see the first pixel showing up is over 6x longer than a full 3Delight render.
Once I get a newer machine, I'll play with Iray some more. And I'm not saying I won't play with it at all, but for those of us with limited time and limited equipment, it will be when I take a vacation day... yeah, right. My last vacation was in 1988. Hah.
Does the registered Dynamic Clothing plugin (with the physics and everything) work in 4.8 yet?
Either it doesn't, or I can't figure out how to activate it. ;)
