...sadly the only character who is fully optomised for Iray (skin eyes, hair & all) is Leela who is seated at the organ with her back to the camera. For everyone else I just applied the base Iray Uber and G2F shader without doing any detailed tweaking to cut down the render time as I was on a tight deadline.
Experimenting a bit. Trying to get good backdrops, and... there's something about quiet night-time scenes that appeal to me.
It occurred to me that the only thing I needed for a 'night time' backdrop was making a suitable cloudy sky and that I could just add in the stars instead of trying to render it all together. I did a fairly basic sky in Carrara, futzed with it, then put it in moonscape and some water (which ended up as titanium metal with some ripple patterns, heh)
title: Tough Guy
This is a render of a my own hand spun g2m character & using merchant resources skin set for Genesis 2 male I've been working on this guy for a while .
rendered in Iray with HDRi There is a very wll hung version of this guy here ...( Well Hung Guy)
I just assumed, based on the title of the image, (and the toy-like colors of the horns,) the characters were intended to "clang" (clash) with the rest of the image. If that wasn't your original intent, then it is a shame you didn't have more time before the deadline. But... I like it as is. I find the characters to be a tongue-in-cheek contrast to the whole majesty of the pipe organ. It is a fun image.
All these Fantastic Renders! Been away for a while.....Life getting in the way of my Art.....finally broke down and got GF3....decided I liked the Vyria for Arabella 7 character the best for now.....here she is as My Maker......combined Wild Hair with Christina Hair, attempting to get similar hair shades....
Don't you just love working with reflections, At first glance I thought you have firefly all over the render , but at a closer look I relies they were stars and they were reflecting off the water. thats nice work. :)
Love your Vamp. thats the first one I seen that likes being in the bright light .. that will make her much more dangerous than regular vampires.. Nice render :)
I like how the sun shines in the background. She does look great.
Thanks for the comment .. I just love her curves and how much meat she has on her bones. . Though I am not able to render her in Iray using the Castle dungeon because I only have 24 gigs of rams and it went way over that trying to render it ,My NVIDIA cards handle it just great and I can render the castle without any characters, and 4 light shaders. but as soon as I add Natasha into the mix..my Ram usage went over the 24 gigs I have and and crashes Studio. So I'm going to have t play around with it for a while to see how come its using so much Memory. . I don;t even think I can install any larger Ram chip sets into my system so I'm gonna have to find a work around for it. Other wise that Castle dungeon really looks great just uses a ton of Ram memory
So there is no way to remove rooms and props that are not needed?
Also, you can play with the texture threshold under Render Settings>Advanced. Maybe that will help you cut down on the memory usage.
Twenty-four gigs for a figure and a dungeon scene sounds like a lot of memory usage to me, as though it isn't normal.
Yea I just got it last night so I have not tried removing sections and turning off things that was with the full load.. I would have thought 24 gigs of ram would be enough to render any daz scenes but it appears something have a heavey work load.
Also there ws no defualt 3delight version of the dungeon castle in the pre load scene folder. so I had to use the 3delight mats that were proviaded and I re save the set completely changed for 3delght back in the main scene e folder, as a scene asset. so now I have both versions 3dlight and Iray as a Pre-load complete scene.
the detail on the dungeon castle is also very good Hightly details so I may need to turn off a few things before i can render it with characters in the scene ( working on that now )
Okay these are some screen Shots I took of the process of rendering the Castle Dungoen Iray model with Natasha for g2f and Iray . I am pretty much sure everyone know now what I have for a system by now I brag about it enough. But just for the record.
Intel i7 Ivy-bridge 3.333 Ghz 6 core processor. over clocked at 12% Liquid cooled
24 gigs of corsair SDRMM 12 gigs & DDRM 12 gigs memory combo Fan cooled.
2 - EVGA gtx 980 cards with 7 gigs each of useable memory. (they say 8 gigs each but its really only 7 useable) Over clocked @ 20% liquid cooled
1- 524 gig independent SSD OS drive. Networked in private DRM/cloud configuration server set up. I -2TB HDD Drive that hold my content . with to 3 more 2 TB Hdd drives external connected by USB3.0 Hub So I can use my system as a Private cloud server for all my devices even if I'm away from home working.
Each image below is the steps I used and a resource monitor showing the usage rates. I also included 2 completed renders one using the default setting with no characters the other using just one character and raising the lighting vaulues. No propsI can not render this set up with another characters . I added a g2m to this scene and it over loading my memory at a 100% at 40% of the rendering process and crashing the studio program. I should mementioned I rendered theres at 720p
I'll work at it some more to see how far I can actually push this set on my system.
It is obvious that DAZ Studio isn't using as much memory as you claim. I think you are confused. Forget the Resource Monitor and use the Processes or Details list and sort according to highest memory a process is using and you will have a clearer picture as to the amount of memory each is using. If your cards each have 7 GBs and if what I read is correct, that you can't combined them, then you can only use about 7 GBs to render a scene with your GPU.
I think your confusing my Gpu memory with my Sytem Memory .. My gpu is 8 gigs each SLI at 16 gig 14 usable. My System is 24 gigs with prefetch truned off. This scene set up render uses 82% Of my system MEMORY.
The gpu memoery seems fine its only running at 55% according to EVGA Precious X16 GUP monitor .. Studio crashes during rendering this scene when I have more than 2 characters in the full scene set because it uses all My 24 gig System Memory not my16 gigs of GPU Memory.. I'm working on the same scene using 1 character and one prop a lighted torch and see if that set studio crashing
According to what I have read on the forum, you have to turn off SLI. Am I wrong? That you can't combined the video cards for rendering with Iray(?).
I understand what your GPU memory and your system memory is. Use the Processes list to find out what else is using memory while DAZ Studio is rendering. That's what I am suggesting.
SLI is not used, and it is recommended that SLI be turned off. Even if you fail to turn it off, it will not combine Video Ram on SLI cards.

So basically, when the memory use maxes out Ivy's GPU-memory it crashes. Rendering with just the CPU should allow the scene to render without crashing. It could be that the castle is a memory hog, but we can't tell without knowing what other processes are using up memory, if at all.
Ivy, where did you find EVGA GTX980's w/ 8 GB? When I look at the EVGA site, all the GTX 980s have 4GB.
It shouldn't. It should just fall back to the CPU. (Which was a problem in 4.8 under some circumstances and is fixed in 4.9.
Yes they do. Getting really good render times. Curious to see how they will improve more when I install 4.9.. nother http://fav.me/d9eui6a
Okay this one has 1 prrop added. I changed some settings in my GUP clock and shut off some proccess I had running.. it was much better This was running at 85% Physical system memory. gup was still at 55%
It also rendered at 1/2 the time at 10.23 minutes.
Next I going to try to add G2M back into the scene and see if that crashes studio . its not my GPU memory its using it the system Physical memory and even if it ws using all my gpu thats a heck of a lot of gpu at 16 gigs.. to be using with 1 character at 720p isn;t it?
Read what DAZ_Spooky just posted "it will not combine Video Ram on SLI cards." Iray will only see the memory in your first GPU and that's all it will be able to use. Which makes sense when you say only 55% of GPU memory is being used, as in 16 divide by 2.
well thats a easy fix .. I'll just pull my SLI socket off. and reset my PCI and shut off SLi BRB
Not required. You can turn off SLI in the NVIDIA control panel.
It see the memory on each GPU, it does not combine them.
So for example youhave a 980 with 4GB of Ram, a 980ti with 6GB of Ram and a Titan X with 12 GB of Ram.
If your scene fits on 4 GB of Ram then it will use the CPU and all three cards. If your scene requires 5GB of Ram then it will run on the 980ti, the TitanX and the CPU but not the 980.
If your scene requires 11GB of Ram then it will run on hte TitanX and the CPU.
If your scene requires more than 12 GB of Ram then it will render CPU only.
Yeah, as I have read before. It would seem that Ivy was not aware of it. In Ivy's case when I say it will only see the first card's memory, it's just a quick assumption. Hopefully Ivy's got the gist of what I have been trying to explain.
And it would seem that Ivy had other processes running using up memory.
BTW, Ivy is a she?
I've just loaded it up and added a figure. It is taking 5.8 Gb of memory according to Task manager and is rendering, CPU only as no card, at the moment.
Experimenting with crossgender morphs (yay GenX2!). Not perfect, but hey. Figure is actually G2F, modified to look male. Might be useful for female-designed content, though I'm not sure it will actually be better than using autofit.
Okay I was just barely able to get this rendered using 2 gensis 2 characters and the castele dungeon all in Iray Head lamp off
I posted some of my settings nd processes as well this render was using 20.5 gigs out of 24 .. ... whew...lol
