Pause a rendered image and continue later.

Good morning, is it possible to save an image that did not finish rendering and continue it from the point where it stayed the next day?
Greetings and thanks.

Not as such. You can stop an Iray render and resume it later, as long as you leave the render window open, but you can't save the render in progress and resume it later after closing the window or application.
It would be a nice feature...
That's for sure. I know with Corona you can do this by saving the CXR and EXR files before closing. DAZ should think about something similar with DS. Iray probably doesn't support it though.
It is possible to "pause" the render by pressing "cancel", leave the render window open, and then either put your computer to sleep or hibernate.When you wake it up, you can resume your render by pressing resume on the render window, and begin rendering where you left off. Be aware though that on rare occasions DS may crash doing this (I think it's happen 2 or 3 times on me over the years). I also use a laptop, which may be better at this than a desktop (but it really shouldn't matter).
I'm not sure - my worry would be that Sleep/Hibernate may preserve the contents of main memory I suspect it would not preserve the contents of device memory, so you might well find that a GPU render crashed on resume. I seem to recall there were issues with some application having crash because the data didn't match after waking, but that may not have been DS and may not have been an Iray render if it was.
It works to some degree. I haven't pushed my luck beyond doing two simple scenes at the same time, although I have a sense that the simpler the scene, the more of them you can (in theory) be working on at the same time.
I have also had multiple renders paused while another one is going. Useful for certain tweaks like moving an object slightly to cause the shadow(s) to be altered, or when you're pretending it's Ingrid Berman on the screen (or Grace Kelly) and you want to alter the corner of her famous smile or the eye position "just so".
Stopping and resuming doesn't always work on one quirky old computer I have (8 GB of RAM and Windows 10) - twice this year I have awakened the unit from a long sleep and presto - Daz Studio was shut down and it was goodbye to any further work [on that particular render] without starting over. So if you're messing around it's wise to save the last render to disk with a temporary file name eg. "render1" or "render2-in-progress".
I do these things routinely on various laptops and at least one old desktop - nothing fancy but it has an SATA drive in it, and I found that installing a brand new ATX power supply helped as well.
IMO Windows 10 "Sleep" is not as good as Windows 7 "Hibernate" was.
