Been trying all day to get a scene to render... try 6 times to get an IRAY render and have to restart my computer each and every time because my computer locks up as soon as I hit render, the same thing happens when I try an Open gl render... then I go down to try a basic render only to get a black render every time when the light is set at 100% and pointed directly at the subject with nothing in between them..... Getting frustrated as hell here..... What a way to waste a day.

Does this happen for any scene you try to render or just the one specific scene?
I only tried the one, I built it today, so I figured it was not the scene.
What's in the scene? What lights are you using?
Well when I was trying Iray, I had iray lights with all of them turned off except the one that would hit my character, and eberything in the scene was turned off and invisible except for what showed in the render screen. The same goes for the open gl and basic try except for i changed the lights out with regular lights, (A single spotlight actually)
Basically, more lights in Iray helps speed things up, not slow them down. You're making the computer work harder (put simply.) I'm not trying to be insulting, I don't know what you know, so this may be all a waste of time to tell you- but here goes.
Use the default Iray HDRI that loads, turn on Dome and Scene in Render Settings, then in Tone Mapping do a Film ISO of 145 (do that first, as if you change the ISO, you move the other slider) and THEN do Exposure Value to 13.50 For whatever light you have in the scene, select it in Scene then in Surfaces, go to Luminance and put it at least to 25,000 lumens. See what happens.
If you aren't getting any results or are, but they are dark, turn your Exposure Value down to 13.25. Turn the lumens up to 50,000. Have you tried any of this? (Changing exposure value/ ISO/luminance?
LOL I have not tried ANY of that, as I have not a frigging clue about IRAY and I have actually not rendered anything in months. Where do I find all this stuff? the only thing I could find was the advanced tab which didn't have but a couple checkboxes that did nothing for me , but then again as I said I know nothing about how to work with it.
I appreciate the help I have been given and any further help I may get, the last time I actually rendered something seriously was back before IRAY was added and my memory is not the best after a while so I tend to forget things, but then I thik they moved stuff around on me quite a bit as well.
Here's a step by step and you can do this for your scene. This is my reference post for my Art Studio thread, there's tons of handy ones for many things you may want to tackle. (I was a training professional / professor, etc- teaching is my thing- so you get baby-stepped through it.)
@Malandar - Check your Private Messages. :)
Thanks, I will have a look.
Okay, I have checked several times and there is nothing there.
Are you checking in the right place? Click on the gear icon at top right of the forum page (the one on the darker blue-ish line), and then in the drop down list click on Inbox
Ah thanks, not used to this version of the forums either...
You haven't mentioned how much RAM you have or what operating system you have.
I can tell you you computer will become very unresponsive when rendering if you don't start the task manager before you start your render & go to the details tab and then select DAZ Studio in the process list and right click with the mouse & 'set affinity to be one or more more less CPU cores/threads listed (eg mine computer lists under affinity - All core, 0 core 0, core 1, core 2, and core 3. I uncheck core 3 but I could uncheck core 3 & core 2 too for example or all of them although I wouldn't want to do that).
Got your mesage and replied.
Windows 7 and 12 G of ram.
Okay I saw something that makes me wonder if I have been wasting my time the whole time. I saw someone say that you can't do an Iray render unless you have an Invidia Vid card. if that is true I am boned. Mine is a Radeon...
I had been looking in entirely the wrong place until Chohole told me where to look. lol
I use a laptop with Intel 4000 graphics and don't have ant problems with Iray other than loooong renders :) You don't 'need' a Nvidia card it just works faster with one :)
Yup....the only advantage is speed. The CPU render will give the same results in the end. :)
Okay a reason to continue then. Thanks.
