Quality settings

Hi everyone. I needed to understand something about rendering quality: for a project intended for printing, for example, in the 6 x 9 format, what parameters do you recommend for rendering? Thanks

    The first consideration is going to be how this is printed. If you're talking about a personal printer, 200dpi may be sufficient. For professional printing anywhere from 300dpi to 600dpi, maybe more. DPI is "dots per inch" with a "dot" being essentially the same as a pixel. So a 6-inch by 9-inch print would require a minimum render resolution of 1200 x 1800; 1800 x 2700 would be even better.

    However, if this is being printed professionally, you should find out from the printer what dpi they require.

    As for the render settings, I recommend the following for any render. In Render Setting->Progressive Rendering:

    1. Set Quality Enable to Off.
    2. Set Max Time to 0, (zero.)
    3. Use Max Samples to control how long the image renders

    With the above settings, the only stop condition for the render will be when the Max Samples has been reached. If the image needs more rendering, it's a simple matter of increasing the value for Max Samples and resuming the render. (This assumes you do not save and close the render window.)

    Thank you for your kind reply. So I made the wrong settings here, did I go too far? it is 8 hours and it is still at 0% triste

    Yeah, I'd say those settings are WAY too high (the ones in your screenshot). I'd try L'Adair's suggested settings.

    I think you're best bet is to cancel the render and start over. 8000 pixels square will really tax your system. I have a GTX 1080, and I wouldn't attempt that size.

    Chances are really good, you're rendering CPU Only, too. There are many variables that can increase the amount of RAM used, and size of the rendered image is one of them.

    If you cancel the render, change the dimensions to what you need for your print, and make the changes I recommended earlier, (start with Max Samples of 2000,) your image should render much faster.

    I recommend restarting Daz Studio after you make the changes and save the scene. I find that can often help speed up render times to start with a fresh reboot of Daz Studio before rendering.

     Hi, sorry if I'm taking up this topic again. I changed computers based on my budget, and now I have a 2060 GPU (2080 was too expensive for me). I would like to make 300 dpi for printing. Do I have to increase the quality beyond the settings you suggested? thanks a lot

    Take the size of your print and multiply it by 300 and that will give you the render size for the print size.

    e.g  a print of 24 inches by 12 inches would be a render size of 7200 pixels by 3600 pixels etc. Obviously that size can be printed smaller if needed or larger if you change the print DPI so lowering it to 150 on the printer would give a print size of 48 inches by 24 inches (approx.) for the same render size.

  • dannagiusy64dannagiusy64 Posts: 477

     Ok, but I saw that in the rendering settings there is the possibility to change the quality. I raised the quality and made a 96 dpi rendering ...

    The 96 DPI is the resolution of your screen, it has nothing to do with printing. Your printing size is based on the pixel dimension of the render, Height x Width, divided by the print resolution set in the printer or your image processing programme, e.g 300 DPI, 150 DPI or even 600 DPI. Each gives a different size of print image from the same pixel dimensions. They will all look the same on your monitor as the monitor is looking at PPI, pixels per inch, and not DPI, dots per inch.

    This might help in understanding.

    OK thanks. But I have seen that many of my renderings with the settings suggested above, when they are finished, always have dots, a grain that disturbs and to hide it I always have to apply a filter with photoshop like oil paint

    This works quite well to denoise as well
