    Just to throw a monkey into the works for you. http://shop.lenovo.com/us/en/laptops/lenovo/y-series/y50-touch/?sb=:000001C9:00014C2C: is the newer model of the laptop I have (I have the 860M with 4GB and no touch screen.).

    Note that mobile graphics cards have half the cores of a desktop card. This should also save you enough money, to pay for half a desktop machine. LOL.

    I am avoiding touch screens because of the heat and the battery drain. Plus I doubt I would really use it. I do have two fairly beefy desktops that I work on regularly, but the laptop is for traveling. As well as when I decide that my back can't handle sitting at my desk for another 18 hours. :)

    @legionair
    your name sounds french (me too ;-) )
    I have this laptop....for 3.5 years, and still up to date (with a i7 3820). It always goes with me as a moving desk ;-)
    the bad side is that mine is radeon one, too bad for iray.

    Alienware is expensive but according to my experience reliable with high quality. you can't go wrong especially with the 980 wich has many cuda cores (but less than the desktop one 980gtx), it is closer to the 970gtx


    The "Legionair" name has been with me for years and years now. It originally came from the Legion of Superheroes comics. Before they got re-booted a dozen and a half times.

    And that is good to know. I want to be able to compose scenes with as little lag as possible, then render test views in a reasonable amount of time. Then I will probably transport the working files back to my desktop for fine tuning and final rendering.

    I would never go again for Asus laptop, the last powerful Asus Republic of Games diet after 1 and half year while abusing it by rendering with GPU too often .. literately melted and it has double separate cooling for GPU and CPU .. in short it was waste of money and I learned my lesson

    your new specs seems promising , nice choice !

    Thanks. It ends up being a pretty penny, but if I can get three or four years of use out of it, then the price is much more reasonable. So I would rather err on the side of more expensive.

    The Alienware stood out to me because of their attention to the cooling aspects of things. My current laptop overheats way too often to be healthy.

    do you know that msi and alienware offer an option to use an EXTERN GPU? that is a solution for you, knowing that your laptop can have a possibility to "upgrade" (but yes, expensive solution)

    Yep. One of the reasons why I was looking at Alienware too. However I read that once you plug the external GPU in, power is turned off to the internal one. So you don't gain the extra GPU power, you just switch it out.

    It does make for reasonable future expansion.

    I really think the best thing to do here is to discuss the graphics cards in the thread(s) Pam pointed out:

    since there was a discussion on it all ready (helpful keeping the info in one spot) and to get this one back to its purposes of showing renders and discussing surfaces and general tips and tricks etc. It also alleviates any confusion to newer members who may misinterpret the graphics cards discussion to mean they can't use Iray unless they get different hardware and leave that topic for those who actually are looking for or in need of a new graphics card or computer to have a place to discuss that specific part of Iray performance in depth.

    I have an Alienware X51 2012 or so with an aftermarket GTX 970. Total cost is somewhere in the neighborhood of $1300-1400 nowadays?

    Not cutting or bleeding edge, by any means, but a credible personal computer, and it renders stuff reasonably fast.

    I think having a AMD and NVIDIA card in the same system slowed thing's down.

    That's a 100% finished @ 95% convergence in under 3 minutes!!
    Hands down beats the 4 hours 3 minutes it took to render on CPU only!

    Oh, that's while also installing the Defiance game in the background.

    Well done Mark , nice timing
    the wrong material settings can decrease the speed dramatically from what I tested yesterday especially when using not converted 3Delight materials

    That is cool render , you used again the character I liked before she looks really nice
    sorry for the long 5 hours CPU time but it was worthy I guess , I adore your patience :)
    Thank you.. my birthday is exactly in 2 weeks but my pre-birthday yesterday was amazing lol

    I think you can set the CPU usage under Task Manager but it will lower the total performance of DS .. I wish there was speed rendering options like in Octane to set up exactly how much power you want to use at once, it bother me also in Photoshop as it use all GPU and all cards

    Cool video! Congratz on getting those titans and I hope you had a happy birthday :)

    I tried a bigger scene. This rendered for 5 hours with 100% CPU. Its still grainy because I stopped the render at 80% with almost 6000 iterations because I needed my computer for something else and I couldn't even open a browser lol
    Is there a way to set how much CPU Iray can use? I have a geforce 770GTX but its useless here.

    what would it cost to own 2x TITANS at 12GB?...roughfly...


    (just wondering) :roll:

    Just over $2000, if you shop.

    That's still 4-6 times worth (or more) of monthly rent for most of us here.

    I wish I lived where you do. $500 a month here in the Seattle area is a garbage can. With no lid. Plus utilities. ;)

    of course you will get the same results no matter you render with CPU or any other cards, I don't understand why the topic about , it seems like other people don't understand the technical side here and subject of matter in first place . With better hardware you win only the rendering time and nothing else and that is all about ..
    The Camera don't take pictures.. You do ;)

    On the Graphics Card discussion, it is worth note that having to render using CPU (as I am doing) is perfectly good if that is what you have to work with. That is the real power of Iray IMHO, you can use it either way with success. If you have, can get, can afford a nice graphics cards and want more speed and performance, then by all means get another card (If and when I can I probably will) but I've been rendering promos, texturing/surfacing in Iray, etc all using CPU Only and have gotten very good results.

    ..this is why I need to upgrade the memory on my current system. 12 GB was fine for Daz 3.1A and maybe 4.5, however the programme has become more robust since then. I am finding it more and more difficult to keep a scene in memory during rendering without the process going into swap mode (I also clear memory and unused shaders before rendering).

    The scene with the car and Yosemite HDRI I mentioned about last night stayed all in memory during the render process and still took just over an hour in CPU mode to reach 100%. After I launched the render I did get a "High Memory Usage" message. but noticed that it never hit the HDD through the entire time. Now were I to substitute a mesh setting with ground and plants for the HDRI, that HDD LED would be lit steadily all through the process as I'd be pegging the available memory and sent into swap mode until the render was finished ....maybe six to eight hours later. Hopefully another 12 GB will help this situation for now. until I can afford a GPU that is able to handle the scenes I create.

    If the the 980TI had 8GB (as was originally rumoured) instead of 6, I would probably find it sufficient for most of my work.

    I don't know if this is an issue the old hands are fully aware of, but it caught me by surprise.

    Using Super Dress and Super Leggings, I gave my character leggings that came just below the knee. But when I rendered the scene in Iray, her legs came out really dark. After a bit of trial and error, I was able to determine setting Cutout Opacity to 0 didn't prevent the invisible sections from affecting the render. I suspect the hidden sections are casting a shadow. The DAZ Rose has the same problem. The petals, calyx and leaves all have a hidden "back" for 3D printing purposes. The white rose came out gray.

    The solution is quite simple, really. Instead of setting Cutout Opacity to 0, set it to 1.00 and then add an image map of solid black.

    Here is the same scene both ways, though one was rendered without the Island Grounds so it's missing the shadows from the tree.

    Edit: As you will see later in this thread, it turns out the Render Mode was set to Interactive. When set to Photoreal, Cutout Opacity works as expected. (I have no memory of changing the render mode... I think I need to sleep more, play with DAZ Studio less. lol)

    After a bit of trial and error, I was able to determine setting Cutout Opacity to 0 didn’t prevent the invisible sections from affecting the render.

    The likely culprit is that the black on the transparency map is not absolute black. Iray is very picky about that. That is why some hair textures don't render the same either.

    It is true Iray is picky about transparency maps, but it doesn't apply to the Super Dress and Super Leggings.

    This product does not use opacity maps. Each garment is broken up into sections and a section is either visible or not.

    If you apply a style from the Surfaces>Presets>Materials tab, unused sections are set to an opacity of 0. In the case of the leggings, there is a separate option to clear the legs, as well. I think it's a very clever product.

    If you look closely at the images, you can see quite a difference in the shadow on the step from the rose's leaves. The image on the left has larger shadows. Iray isn't cutting it out, because there isn't a map in the Cutout Opacity setting. In the image on the right, the solid black map has been added, and the back of the leaves are not casting shadows.

    I just tested and sett Cutout Opacity to 0 does not cast any shadows on the model no matter converted to Iray shader or not , it maybe something else on the hand here but I am sure not Cutout Opacity , you may have a texture plug in in the opacity that is not 0 black

    I guess then that Iray prefers maps to 0's.

  • MEC4DMEC4D Posts: 5,249
    edited June 2015

    Yes it is ......the Cutout Opacity purpose under Iray is to hide the polygons and only White 255 or Black 0 colors should be used in the maps and not shades of gray color .. it is not the same way Opacity channel that was under 3Delight , as in physical world something like that does not exist.

    I had the same issue with hair caps. I tried everything I can think of to get rid of the shadow but it never went away. Not on Iray based shader. not on Subsurface. Not on Uber. Not on default shader. Not opacity 1. Not opacity 0. I tried blacking it out. No go. I tried inverting the black. No go. I came to the conclusion it has nothing to do with opacity. Something else is casting it. So I turned all my settings to zero. Still no go. I ended up having to find another wig because I tried for over an hour and a half to get rid of the shadow caused by something that was supposed to be invisible.

    Even if that were true I need to be able to see the hair cap. To give the actor a hair line. Some parts need to be visible while others don't. You know what I mean?

    I know what you talk about .. that why if you getting any issues the first thing is to check the opacity map that also need to be gray scale gamma 2.0 and not black and white RGB map
