Thats not working..eg I see dome orientation and rotation, what I want is a dome scale, to shrink or enlarge the actual map plugged in by environment map.
And if you need more speed, you can throw hardware at it. If you really want speed you can throw an NVIDIA VCA at it.
If you don't throw hardware at it, for most scenes, providing you properly light your scene in 3Delight, the render times are, on average, the same. You have lost nothing in terms of speed, but gained the ability to increase your speed by throwing money/hardware at it.
Comparison. Same computer. Lit by a single HDRI, in the 3Delight render the HDRI was placed on an Uber Environment 2. Same hardware, same HDRI map. The Iray render took 18 minutes, 23 seconds. Iray (CPU only), the 3Delight image took 72 minutes 12 seconds. (Note this is a straight load and render, no changes were made to the surfaces.)
Is it worth the extra wait time?
So, if I'm reading this correctly, Iray is almost 4 times faster in this one scene than 3Delight just using only the CPU and not the video card?
Zev, try a Finite Sphere and you'll get some options for Scale Multiplier and Radius.
Can you explain a little about how you used "bounced light" in that render?
OOO ...needs install manager
Will install manager mess any of my previous content up if I install it just for this Beta?

Thanks for the clarification and reference to the color coding. I believe you are correct about the "info" page. When I copied the address from the browser address bar, it must have gotten truncated. I'll just be patient on the presets page being worked on.
Oh Iray bounces light by itself. I just made a scene to test how it lights up objects. I liked how it lights up the legs from the sun on the ground. Bleh the radius and scale multiplier is just adding wierd colour tints lol, but scale looks the same:(
...OK, that makes me concerned if there will be any new conflicts with AoA's Advanced lights and effects cameras when using 3DL..
I had to try it. I just HAD to try it...
and WOW !
I was SO FRUSTRATED that OCTANE didn't have a DS plugin usable on mac that i was this close to install windows on my mac pro.
Thank you DAZ for keeping Windows away on my Mac :)
The quality is amazing.
I'm aware we're just in beta, and things might change/improve but this is a great improvement !
THANK YOU DAZ !
I'm having problems rendering scenes with skydomes. Even though the "cast shadow" paramater is set to off on the skydome, it seems to render as though it was casting shadows, thereby rendering the scene completely dark. Is anyone else experiencing the same?
Huh, that is weird then. Hopefully someone else can offer a fix.
I do like that render because it has a bit more of a fantasy look than the often washed-out cold realism that photo-realistic renders have. I'm still really on the fence about this system because I'd really like to use realistic lighting and materials, but not end up with the typical HDRI sterile feel that these sorts of renderers give. Photorealistic renders are really tough to postwork well too, so it will definitely be a challenge.
None that we are aware of.
...apparently from what I have read here there have been changes to the shader mixer which could impact how the current build of Reality4 sees and interprets Daz shaders. Paolo has already issues three patches to clean up issues some that arose from 4.7.
Faveral, are you using a skydome prop like the one in your Medieval Docks? Others have said that you have to turn it into an emitter and raise the K value really high, but I don't know the values offhand.
...OK, that makes me concerned if there will be any new conflicts with AoA's Advanced lights and effects cameras when using 3DL..
Why? The new bricks wouldn't be in any 3DL shaders, lights, cameras, etc, and you don't use AoA's lights with Iray.
Typically you do not run dual cards in SLI mode for GPU rendering.
Iray doesn't support turning shadows off - it's "faking reality" so objects always cast shadows. As noted, make it an emitter using your textures and (I've been told) a luminance of 9kcm^ and a temperature of 6,500K
Hmm, bearing this in mind, this doesn't sound like it'll be good for my 2GB card. To my mind, the IRay engine would be best off as an optional plug-in like Luxus is then we're not stuck with something taking up hard drive space when we're unlikely to use it. Either that or have 4.8 Standard without it and 4.8 Pro with that feature included. That way there's a version that everyone will be happy with.
CHEERS!You just said you have an AMD card, so your card won't get used anyway.
A New GT 740 with 4GB of RAM is around $100.
And, on average, as long as you light your scenes, using just CPU, the render times are equivalent between 3Delight and Iray. Using just CPU for rendering gets you the same results as using 4 K6000 (12GB) Quadro cards, you just get the results faster with the cards.
...however as I understand VRAM is not stackable for rendering purposes so you will only be using 12GB from one of the units. The extra 15,000$ just to get 4 x the CUDA cores is a bit extreme.
...thank you for this information. When I read there were changes to the shader mixer I had my fears. You just confirmed them.
Wondering if it also made the rest of the Atmospheric cameras useless as well.
Guess I'll be sticking with 4.7 as I don't have a powerful enough Nvidia GPU anyway to really give IRay a good test anyway..
Nope - it only touches what it installed. :) It will say everything is available for install because it has no record of installing it. Just follow the directions on the DAZ Studio Beta store page and you will be fine. :)

Thanks, forgot about that (my brain is still in gamer mode 9 times out of 10 lol). I updated my post.
The beauty of it is you have a choice. You can swap renderers to suit your needs. :)
Kat
Okay, I solved it. The problem was that I hadn't updated to the latest NVidia driver. I now have the recent version installed, and the GPU rendering works like peaches. :-)

If you go further and read the follow up replies, I told him to reinstall the AoA lights into the beta as they need files that install into the application folder. He did, and they work fine. :)

Kyoto Kid, you can use Iray with the CPU, you don't need GPU. If your system can handle 3Delight renders, it can handle Iray.
Just some numbers... I am using a Geforce GTX 660.
If I use CPU only, I render 19 iterations of Iray in 2 Minutes.
If I use GPU only, I render 10 iterations of Iray in 2 minutes.
If I combine them, I render 24 iterations of Iray in 2 minutes.
So, the card gives extra speed, but if you have a half-way decent CPU/RAM, then the Iray is pretty fast just using that.
...however as I understand VRAM is not stackable for rendering purposes so you will only be using 12GB from one of the units. The extra 15,000$ just to get 4 x the CUDA cores is a bit extreme. You understand incorrectly. Each card uses its own RAM.
So for example if you have a GTX 570 with 1.25 GB of RAM, a GTX 680 with 2GB of RAM, a GT 740 with 4GB of RAM and a Titan Z with 2x6gb of RAM (Note the Titan Z, the K80, the 590/690/790 are all two cards on the same slot, so you have to divide the RAM in half, one half is dedicated to each card on the slot.) here is how it works.
If your scene fits on 1.25GB of RAM or less then all the cards plus the CPU will participate in the render with all their CUDA cores.
If your scene fits on more than 1.25GB but less than 2GB then the GTX 570 will drop out and the scene will render on the CPU, the 680, the 740 and both halves of the Titan Z.
If your scene takes more than 2GB but fits on a 4GB card then the GTX 570 and the GTX 680 will drop out and the CPU, the GT 740 and the Titan Z will all render.
If your scene exceeds 4GB but is less than 6GB then both Titan Blacks, that make up the Titan Z and the CPU will render but the other cards will drop out.
If your scene exceeds 6GB then all the cards will drop out but the CPU will render.
If you have K6000, and/or K40 cards then every card will render unless the 12GB on the card is exceeded.
Note you can mix any combination of Quadro and Tesla cards, as they use the same drivers. According to NVIDIA you can only mix Geforce cards with other Geforce cards due to slight driver incompatibilities. Do not mix Quadro or Tesla cards with Geforce cards, it is an unstable combination.
If you have multiple cards and one of them has a low amount of Video Ram, like the GTX 570 in the example above, you may be better off turning off that card, placing it first in your computer and plugging in your monitors to it. This will free up the maximum amount of RAM on your other cards. If you have a Intel Processor with a built in Intel Graphics card and the correct drivers, it might be in your best interest to have your monitors plugged into the motherboard ports and run by the Intel 4000HD to 5000HD graphics chip on the Processor and free up the maximum amount of RAM on your video cards.
You can test it, but you won't be able to do any speed runs. I'm using an older box for testing (i wouldnt ever have DIM installed on my real computer) and I was able to get a good understanding of what the current IRAY implementation is capable of. it's pretty promising overall.
I'm going to hold off though for a variety of reasons but plan to do a few tests here and there.
What Spooky is trying to say is simply this: You don't get more video cards for more ram, you get them for more cuda cores to speed things up.
But the (ram) bottleneck will be the card with the least amount of ram. You can disable cards you don't want to use via the software.
Why? The new bricks wouldn't be in any 3DL shaders, lights, cameras, etc, and you don't use AoA's lights with Iray.
...there is also a new version of 3DL with this update.when that last happened (4.7) it caused issueswith flagging SSS shaders and made several of the effects cameras useless.
...and I am speaking about 3DL not IRay as I don't have a powerful enough Nvidia GPU to take advantage of the speed of pure GPU rendering.
It's not a Ground plane. It's a simple plane that I enlarged, but it's not a part of the environment. It's an object in the scene.
Second, there is no 'Environment' in the Render Settings. Here's a screenshot of my Render Settings:

Yes, in this one scene. It isn't usually this one sided. but when you use area lights, and/or AO, combined with AOA's Subsurface shader on an HD figure, 3Delight render times really climb.
To be fair I built the scene knowing all this to demonstrate that while you can get faster render times in 3Delight, the newer characters go quite the other way as soon as you add realistic light.

Second, there is no 'Environment' in the Render Settings. Here's a screenshot of my Render Settings:
It only shows up if you are in a render mode where it makes sense. At this time that means you will only see it in Iray render mode.

Ok, was the plane showing black in 3Delight or Iray? You are showing a 3Delight selection. If the issue was in Iray you'd need to switch to find the ground plane (which in Iray, is on by default)
