    Well, the nice thing about the spotlight trick is that you can adapt any skydome to Iray that way. The only problem is if you need a softer shadow than the spot disk will fit (because you need a disk of size N to look right but 2N to make soft shadows) At that point it might be worth using an invisible emitter disk that you can scale. (Which is another option, generally speaking -- just substitute a disk or sphere for spotlight and make it emissive)

    ...basically what I am looking for the same shadow falloff like the Iray Sun produces where an item closer to a surface or the ground will have a harder edge than one further away.

    Distant lights tend to emit rays that are more parallel (closer to what the sun does in RL) than spot lights which is why they are used for the "Sun" in 3DL.

    I also don't understand why there couldn't be different "sky" environments that work with the Iray "sun".

    Does a postworked Iray render count for this thread? :)

    Nice,

    I'm partway through an Iray MAT and shader for Darius.

    CHEERS!

    Thanks. Keep going on your mats for Darius. He is looking good.

    Thanks, I still need to work on the eyes, mouth and teeth, but I think I'm happy with the skin. I tried lighting him using the 'sunny 16' rule and I think he looks great.

    CHEERS!

    Quite nice, but, the skin looks a little flat.

    Yes, I was in a hurry and only applied http://www.daz3d.com/beautiful-skin-iray-genesis-3-female-s

    to the skin and it looks like it does not carry so much details.

    I will try another setup at some point.

    Yeah, I looked at them and wasn't overly impressed. Catharina (Mec4D) has so far provided the best results with her skin settings. I keyed in Iray settings for the eyes on Darius and they look good, though not dramatically different to how they looked before.

    CHEERS!

    Fast lux will be here next Monday! Meanwhile starting to figure out skin settingsin iray by following examples out there. I thought I was rendering this with a converted mesh light. Turns out it was the &^%in headlamp even though I set to have it off in the settings. I Iet it run for 4 minutes but looked ready in less then 2. No mo' long render time MFO. It looks I will be most likely getting a gtx980 popped in the beast!

    Interesting, though I never really did anything with Lux. Iray seems surprisingly intuitive and not the CPU killer I feared it would be, I'm still getting a GPU though.

    CHEERS!

  • kyoto kidkyoto kid Posts: 41,202

    ...yeah it's not bad unless you start creating involved scenes like I do (especially adding volumetrics like fog or mist).  Darker scenes also seem to take longer than well lit ones.

    I have yet to run a proof render of the finished railway station scene which now has 8 figures in it and uses a "wet" voulmetric fog. . I expect that will take at least a full night (and part of the next morning) to finish just at the default quality setting.

    I could really use that 24 GB of memory now.

  • RogerbeeRogerbee Posts: 4,460

    I'm hoping my 16gb will be enough. One thing I did notice is that my CPU, being 6 core, is still reasonably usable during renders. I have been able to have my browser open at the same time.

    CHEERS!

    ...part of the madness behind my "mega beast" design. Duo 8 core hyperthreading Xeons plus 4 Titan Xs (or two Pascal 100s if they come out by then) and 128 GB of physical memory.  I could have several instances of Daz open and still get decent response.

     

    Of course if Reality 4.1 and Lux 1.5 really perform as advertised, then I can render several jobs in background (of course would have to go with a couple AMD 16 GB Greenland GPUs when they come out).

    That's some serious firepower!

    CHEERS!

    ...yeah will cost about 8,500$ (with the Titan Xs) to build.  Prebuilt, it would be about twice that.

    That's some wedge! I've never totted up how much I've spent on my build, I might scare myself!

    CHEERS!

  • Oso3DOso3D Posts: 15,041

    Wow. And I thought my hoped-for next machine was expensive. (I'm aiming at about $5-6k for an Alienware X51 with 1-3 980Tis, depending on my budget)

    I'm expecting only to have blown just over a grand!

    CHEERS!

    Add a zero to Max Samples; Max Time set to zero; Convergence set to 100%. It shouldn't stop at a time as the zero means run forever, as far as I can remember, and should stop when one of the other two parameters are reached.

    This was rendered in Poser and just won 3rd place in the Monthly Challenge over at RDNA.

    Nice going!

    CHEERS!

    Thanks!

    I've swapped out the case and the power supply in the time I had mine and the GPU is next on the list. If I upgrade anything else, I'll gut the case and start again from there...

    ...to me Ailenware is like buying Chopin wodka instead of Luksusowa.  The latter is just as good at less than half the cost for the fancy name brand.  Just went to the Alienware site and the best I could "build (using their  "Area 51") came to over 7,500$ and only had 32 GB of memory a single 8 core I7, three Titan Xs (maximum), one 512 GB  SSD with 2 5400 (not 7200) rpm 4 TB HDDs, and a 1,500 w PSU.  I didn't bother with keyboards, mice, or displays as I already have those. Furthermore, since 2006, Alienware has been a subsidiary of Dell and some feel they lost their "edge" after the acquisition.

     

    The tricky part for my own custom design was finding a good full tower case to put everything in.  Seems everyone's been going to that useless window in the left side panel (where I just want a big fat exhaust fan like my current case has) and LED's lighting everything up inside and out.  I'm not a gamer, I don't need all that technological "bling" that says I am.  Not into rack mounts either as they take up a much larger footprint which is inefficient space wise for only one blade.

    Well, for me, 'build it yourself' is about as good as going and buying thousands of dollars of fine China and then smashing it with a hammer repeatedly.

    Alienware might not be as good as a competent person doing it themselves, but I don't have a competent person here. ;) I agree that they've lost some of their edge, but they are the best 'buy something that will do what it's supposed to and you can return if it doesn't' I've found.

    (Also you can save a lot of money going with 980Tis, from what I understand, which are almost as good as Titans at much less price)

    ...memory wise, not for the level of scenes I create.  I'd still find the process dumping to the CPU a good part of the time, and at 650$ a pop that wouldn't be cost effective.for my needs.  However, by the time I probably have the resources to build this monster, the new Pascal GPUs will probably be available and then I'd possibly only need 2 as they are expected to have between 5,000 - 6,000 cores and at least 16 GB Video memory each.

    There are other custom build houses where I think 5,000$ - 6,000$ could get you more (particularly in the way of memory). I'd shop around.  Some may still yet offer an option for Win7 Pro as the OS .
