SETTINGS For IRAY IN DAZ STUDIO

01 Resolution

Under the Editor section (within the General category), for Pixel Size enter your desired render size (in pixels), width x height. For the Aspect Ratio, enter your desired aspect ratio in the fields in width x height format. For example, if you select 4x3, the render will be four pixels wide for every three pixels high (or 4:3 aspect ratio). For my non-standard size images, I just enter the same values in the Aspect Ratio fields as I do in the Pixel Size fields.

03 Rendering Quality

If Rendering Quality Enable is set to Off, Iray will just use the Max Samples and Max Time settings to determine when the render should stop. With it On, Rendering Quality linearly increases render time each time you raise the number. So, 2 is double the value of 1, 3 is triple the value of 1, and so on. I tend to leave mine set at or below 5. You can increase this number if you really want to try to render forever and stop it on your own.

02 samples and time

By default, Iray is set to go to 5000 Max Samples, and that’s a good start for preview renders, but it won’t be enough to render a finished image without graininess. If your render gets to 100 per cent but still looks grainy, you may need to add a higher value to the Max Samples setting and increase the Max Time as well. Iray will stop rendering when it gets to the lowest (or earliest) of the two settings.

04 Rendering Converged Ratio

As I understand it, the Rendering Converged Ratio is a function of the time and samples counts. I read somewhere that apparently it’s impossible for Iray to get to 100 per cent, so to avoid errors it’s better to set it at or under 99.9 per cent (I use 98 per cent). Tweak this setting if you want to make sure everything runs long enough without resorting to the Quality setting. Click on Render and go get yourself a cup of tea... you deserve it!
