Show Us Your Iray Renders

Daikatana

Playing with the Iray specific skin shaders.
This ran for approx. 10 minutes .
Hardware on laptop is as follows:

Processor: I7
GPU (s): NVidia GeForce GT 735m ( 2gb ddr3 vram)
Intel Hd graphics

8gb system RAM

I' think I am gonna love Iray when I figure out how to better utilize it

Ivy

Clean out the dust it did in deed..lol
I did not no the ue2 did not work with Iray.. I had the sun dial turn up maybe that what was giving me the light then.

As far as cooling goes each EVGA card came with 4'' fan pushing air threw a 160mm liquid cooling unit My PC tower has 4 push & pull 6 inch fans 2 on top 2 on the bottom of the case . sucking the hot air out. of the case.
the my 3800k Ivy-bridge intel processes is cooled with 2 -180 mm Liquid cooling units with 2 push pull a vary speed 4' fans. I think I spent as much on the cooling as I did the pc . I had the pc built by IbuyPower.com
.lol the evga graphic cards were a upgrade last fall from gtx 760 to these babies 2- gtx titans 960s .lol with my Christmas bonus..lol .. its a awesome gaming PC.
I love plying Skrime on it

All I can says is wow! Is this ever GPU intensive...lol

I render this using street of Asian 2 one A6 charter
render size 1920 x1080
UE2 with one advanced distant light
I used the Iray water shader to replace the default water to see how that would come out.

It took 11 minutes to render. But my graphic cards gpu was like wide the heck open & my processor was still rendering at 100% as well.
I run SLI 2 EVGA titans and they were maxed my cooling fans were set on auto and they went 100% ,
then started using extra power from my UPS booster. ..lol

never had my computer ever been pushed so hard..lol poor thing.

Daz 4.8 might be great for single a graphic renders. but if i were to render animation using my GPU I would be very afraid it would kill my graphic cards, or shorten their life... And at $520 each i think I won't be going there pushing them this hard again..
I took a screen shot my evga monitor when the render was about half way done.. wow wicked resources intensive you can see it was pushed to the limit.

EDIT OPPS I for got the screen shot

73 degrees? Good, your cooling is doing what it is supposed to be doing. If it stays above 90, it isn't, but 73 degrees should not shorten the life of your cards.

Notice that the temp was Celsius not Fahrenheit

Celsius to Fahrenheit
73ºC = 163.40ºF

I'm smitten with this DAZ update, so incredible. Here are a couple of my renders, trying out some of the features such as the skin shader and the shadow catcher. Both scenes lit by HDRI, with a spotlight also in the street scene. They each took about two minutes to render with my Titan.

Rendered with CPU as my older graphics card is not compatible. I only have a 300 watt power supply on my HP computer so probably not going to upgrade my graphics card until I get a new computer. This render ran about 50 minutes but as I said my computer is older.

That's really good, I expected something like that would take days on CPU only.

Love how that glistening skin came out.

Awesome work people. But Totte, you can try to sneak that beemer photo in with the renders! LOL... Seriously, I have to look really hard at that render to see that it is a render.

OK, here's one that has no artistic value at all. It would score below 0. It was a test using a few prisms and caustics. :) I have wanted this ability forever!

Wonderful! Does Iray do caustics automatically? Or is it something I have to set up on my own?

If it's like every other PBR (physics based) it should do them automagically.

As for my card (chin on floor) 8600GT. It came out a generation before the concept of CUDA cores, and apparently somehow it has 32 of them :ohh:

Here's my first successful render after some failed attempts.
A pretty simple scene with a couple of quick distant lights.
Used the iRay shader as suggested.

I found a post by SickleYield on DeviantArt where she reported faster speeds with the GPU alone vs. using it together with the CPU.
I have one checkmark available in my Advanced Render Settings for my iMac's 775 GTXM, so I checked that, unchecked CPU and it did provide faster results.

The difference between the 3Delight's render and iRay's quality is remarkable, but not without a strong waiting time.
It is the equivalent of the render time when using all sorts of fancy lights with 3Delight, except it gives a more realistic interpretation of the light with less setup required.

It wasn't until I figured out those settings that I got to appreciate its quality though.

So for animation 3Delight with a simple setup and fast render is probably better, but for high realism iRay seems a better option than going max quality on 3Delight, unless you're going for something specific 3Delight has.

I added a bit of exposure to the image in Photoshop, that's it.

I'm also providing the single distant light 3Delight quick render version for comparison.

Working with organics was starting to annoy me, and I remembered I had a free kitchen pack from inLite Studios. I really want to get my hands on that chess set by AoA.

Everything shaded with the iRay shaders, including the backdrop. I turned on the top-layer on the backdrop so I could get the reflectivity I wanted on the floor. Smooth spot on the front of the ladle is due to my dof on the camera, the front pane is just passed that spot. The env map is an indoor apartment EXR. No other lights, dome only, and camera headlamp is off.

Forgot to check how long it took, less than 10min though. GPU only- EVGA 770GTX 4GB FTW Edition

PulpArtst

My Specs:
AMD FX-8320 8 Core 3.5GHz
2 X Nvidia GeForce GTX 650 Ti BOOST SLI

I decided to go big for my first render. The scene is from my old Luxus setup as it had the 2 light planes more or less in place with the dark grey cube. I didn't subdivide the outfit and it shows. The materials are the Iray G2F on Olympia, then just Iray Uber Base everywhere else and I set the cube to be rather matte.

This was at 44 minutes, 1875 Iterations and 92.72% image converged.

Riggswolfe

I decided to play with Iray a bit myself. I chose to do a Star Trek render as I wanted to see how well the light emitting surfaces would work. I had a hellish time getting the lighting to work. The sun was way too dark, especially if I tried to put in any kind of background and the space backgrounds I have were either blurry or came out too bright looking, especially if they had something like planets in them.

Shasto

Wow that's pretty sweet.:)

You sure make a good case for that card. My render took about 20-25 minutes on my iMac's GTX 775M.

But the quality and resolution were amazing for that time in comparison to what 3Delight can do which seems better for a more toon or fantasy look.

ZarconDeeGrissom

Riggswolfe. Impressive, can make, star-ship. lol

Is that the stock surface maps on the saucer, or all out Iray shader of sorts?

Regarding Caustics: Under Render Settings -> Editor -> Optimization there are some switches. One is to turn Caustic Sampler on/off. Another for Architectural Sampler which does some really cool lighting effects and Max Path Length which I know nothing about yet. LOL!

Anyway, you use Abbe under surfaces to change the aberration of the glass and turn caustics on. It's nice to have this switch so you don't waste processing when you don't need it. Yes, it does increase render times a bit.

jag11

5 minutes render time.

namffuak

Stonemason's new set (part of it, anyway). :-)

All the light is from the two overheads - cranked way up. Total render time was two hours, although I didn't see any major improvement past the first hour. 6-core I7 3.5 GHz and GT 740 with 384 cores. The 740 never went over 1.4 GB and was driving two monitors as well.

Now I need to figure out where the wall lights are and crank them up a bit. . .

Oso3D

Ok, nothing really glitzy or fancy like a lot of your renders, but I'm happy with it...

(just a Genesis figure, even, though it took some playing with Iray and looking at a G2 figure to figure out how to do it right)

Thanks for the info, still working on the install here.

In fact, being able to specify what surface needs to be calculated for such things, allows for far better optimization then just doing the math for everything. Especially for surfaces that reflect the light back out into the sky-dome out-of-view for example.

I think I am going to like this Iray engine.

One bulb at 20W with frosted glass as the lampshade material.

Sedor

Turned the surfaces of the signs and "LEDs" into light emitter, used just a "skydome" for lighting the scene

electricglore

I don't normally post, but I am loving the Iray render engine. I almost bought OToy last month and I am glad I waited!
Anyway, here is my first (final) render, and it still needs work. If anyone has good ideas how to get an emitter into or onto a fire prop that consists of two perpendicular planes, like the ones DM like to use, I would be very interested, mine always either cast no light, or over-saturate, like in this image.
In case any one is interested, the original is 2000px tall and took almost a full hour using two GTX980's, no CPU.

ZarconDeeGrissom

I wish my first dry-run attempt was just as good, lol.

Riggswolfe I have a star-field for you, and I have no idea how it happened, lol.
Render time on CPU only was under two minutes for all three renders. one with 3delight 'Progressive render' 2minuts and teen seconds. The other two was from the same camera, with the spot light on, and then off. Both Iray runs finished in 31 iterations, ... not a few thousand???

3 omniUber area lights (the three big panels), and three spot lights with visible shields in the mirror ball. Yes UE2 was there for the 3delight render, and like Luxus, it dose nothing in Iray... apparently the DZ lights and the Uber lights also do nothing, lol.

I'm guessing this is like Luxus, and extra settings need to be added to the lights for them to function in Iray. Time to do some homework.
(EDIT)
FYI, the test chamber light and surface settings are described here (Initially for 3delight)

You might try first setting it to have the right color with the emitters... or maybe just a bit on the dark side and then put a Photometric point light in or near the flame to send out more light. Maybe set the color on the point light to a yellowish orange or something.

DustRider

Test render 3.

Same scene as the last, I've just been trying different light set ups and trying to improve the skin shader. I definitely like the skin shader sss on this one better than the last render, added a bit of SSS to the hair too. I traded the sun light for a mesh light, and turned the lights in the hall into emitters (eis profiles). Now it's time to move onto another scene that I kind of have a handle on how lights and the optimized skin shader works.
