Saving in-progress iray renders?

I have a render going..it's taking a while...it has a while to go I'm sure. it's going to window. I'd like to get a save of the image as it is now.

Is this possible.

 

If I hit "cancel", I know i can "resume", in theory..If i hit save, it'll save, but close the window and the render.  Is there a mechanism to save and not lose the window?

    Someone else asked a similar thing earlier this week. I believe the answer is that the standalone as the ability to, but the plugin is tied into the software and cannot resume a render after the software has closed. I think you can resume it as long as you do not close Daz Studio (or move anything / start a new render), though.

    I don't know how to, however. It's just what I remember hearing.

    iray has a standalone version?

    Here's the thread: http://www.daz3d.com/forums/discussion/comment/857013/#Comment_857013

    I apologize, I misread it and thought they said iray had a standalone.

    It's academic now, as the big render hit the 2 hour mark, and I forgot to turn the timer off.

    Useing spot render to a new window, l tried pausing and using "save last render", but that just gave me a copy of the big render.

    Don't know if that's just how it works, or if it's different because of "spot render"

    Edit: That works for full renders, not just spot renders.  What exactly did you want to have saved, only part of the render? Can you turn everything off in Scene and do it that way? Not sure what you're trying to do.

    You can't continue a render. But you can actually save the image and then resume.

    I live in constant fear of blackouts. Where I live we have frequent blackouts. Some last for several minutes to several hours (this is why Luxrender is so important for me).

    Actually DAZ Studio will save the image when you hit cancel. You can then click on the resume button and continue rendering (provided you don't close the window).

    The rendered image will be saved to:

    C:\Users\[user]\AppData\Roaming\DAZ 3D\Studio4\temp

    Copy the image from that temp folder and resume the render. In this way, at least, you will not loose all those hours of rendering if something goes wrong.

    nDelphi, sounds like an uninterupptible power supply should be on your Santa list for this year!

    I just have to believe that an update to D|S will come out soon with 1) A fully external implementation of Iray, since it's already an external library; 2) a way to save scene files (how else will they offer cloud rendering?); and 3) a feature that saves state -- Iray convergence data and image-in-progress -- every 5-10 minutes to disk. So at most, that's all you'll lose if the power goes out. (Like it did for me today, and no, I don't have a UPS either!)

    THIS IS ONE OF THE SINGLE MOST IMPORTANT THINGS EVER SAID IN A REPLY! The exact answer for a question that  I've seen, but not answered! AWESOME! thanks!

     

    For mac users, the file location is /Users/username/Library/Application\ Support/DAZ\ 3D/Studio4/temp/render

     

    (just got home from dinner and a movie.. render is at 78.2% convergence after 4 hours with 543 interations (which seems like a small iteration number..is that because of size of picture, 3200x2701, or ammount of stuff in it...there's a bunch) and I'm glad I can save where it's at now, just in case there's a problem as i let it go.)

    I do have some. They don't help if I only have a few minutes to shut down the computer. It still does not help when the power comes back up and I can't resume my render from where it left off before I was forced to shut down.

    Only LuxRender gives me that option right now.

    If you use Sleep mode rather than shut down it should be quicker, and you should be able to resume the render.

    Never thought about that, my brain is always half a sleep. I will have to try it. Will also have to delve into this option in detail as I believe some UPSes have a feature to tell the computer to go into sleep mode automatically.

    I know this thread is ages old, but I also live in an area with frequent power outages.

    I have a IPS that can power my PC (with all moniters turned off) for about 10 minutes, during which time I can start up my generator and connect the UPS to its supply.

    Putting the PC into sleep mode is a hit and miss affair; it's worked for me once but all the other (15 plus, at least where I have tried it) times it didn't work. When the PC was "woken up" it goes straight into a restart despite changing every power management setting I can think off (as well as numerous PC forum trawls)..............

    A generator can be expensive but it also runs my fridge as well as my reptile enclosures and TV/sound system, etc.

    After suffering through 20 years of often daily power outages, I had had enough and got myself a generator; it's so much less stressful to know when it gets windy (or wet and some dumba__ runs into a power pole with their car) that I will still be able to do what I want/need to do......................

    I've had situations where Daz quits/crashes towards the end of the render and also my power has gone out (in the middle of LA.!) but I found a great solution. If the render is starting to look good, but not completely done, I take a full screenshot from my 27" inch monitor. This has saved me a few times. My renders take forever, over night, on my iMac and I take screenshots every few hours. For some reason, the screen shot actually ends up higher res than the plain save! I usually render at about 2400x2000 and the screenshots are often larger although they may not be full frame, sometimes I have to reframe it and sort of crop it in the screen shot because it's bigger than my screen but it's saved me a few times, and the screen shot was very workable. (I always bring everything into Photoshop anyway for post, so even if it's really undercooked, I can do something creative in PS to fix it :)) But often it is completely usable as is. I take screenshots every hour or two. Yeah, my renders take forever! Sometimes I get impatient and just start post on the screenshot, don't even wait for the full render LOL...

    Thanks nDelphi for that useful info!

    nDelphi, you just saved my bacon.  Thank you!

    Can you shut the computer down and then go to the temporary folder, open the render back up and resume?!!

    No. If you shut down the computer temp files are purged. And once the render has been closed DS can can't resume it from a saved image file.

    DS temp files are purged on application start up and on crating a new scene.

    Edited to add: DS cannot resume a render that has been closed, the only way to stop and resume an Iray render is to leave the render window open (sorrry, I missed this part of your post earlier).

    I had to reinstall DAZ and now when I stop rendering the temporary file no longer appears in C:\Users\[user]\AppData\Roaming\DAZ 3D\Studio4\temp although it worked before. 
    What could it be?

    Check the location of the temp folder, in Edit>Preferences (Daz Studio>Preferences for a Mac)
