what Iray render settings do you generally use?

Toobis

I was just wondering what everyone uses in their render settings before rendering a Daz Iray image. I get all systems are different but what Iray settings do you generally use to get the best quality clearest Iray renders from your systems max capability limits? you don't have to list them all if you don't want to but what is the main ones you concentrate on to have the most desired effect here?

Thanks!!!

As I don't do portraits, where you'll probably want to pump up the quality/time settings, so I basically use the DS default settings. IMO far more important is the lighting, skin settings, scene optimsation etc. And of course keeping your scene within your VRAM limit. The thing you don't want to so is sit through long renders at high setting for no discernible benefit to image quality.

I usually go for 15,000 Max Samples, Max Time 0, Render Quality 10 and Rendering Converged Ratio 98 %.
 

Occasionally, I go for 40,000 Max Samples for portraits.

If pictures take too long (> one day) I stop the render once it is beyond 5,000 Max Samples.

Yes, it takes time. I use a Nvidia Rtx 3060 with 12 GB Vram.

I go for quality 2, 100% convergence. 

The sort of images I do don't usually take much more than 1500 iterations, and aren't particularly big (1920 x 1080) and are rarely very dark so the 100% doesn't impose a significant penalty getting rid of fireflys in dark areas. So far, with my RTX 3060/12 Gb, I've seen a 10 minute maximum render time. That shows the simplicity of my images relative to @alienarea's.

Quality 1 and 95% convergence, if I do interior scenes, I set the "cm^2 factor" to 8-10, which gives more realistic light levels with lumen values that relate to real world ones.
If the quality settings are the ones limiting, I would disable them completely and let the rendering run as long as it takes to look good

Max Samples and Time, both at 15 000 

Using 3060 12GB with the viewport maximized to 1920x1200 monitor, rendering at Viewport resolution. Usually interior renders taking less than 10 minutes
I don't bother with denoising, as the renders are noise free even without it.

I use the default settings on the progressive rendering tab, unless I need to up the time...which I haven't since moving to the 3090. What I do change is the texture compression...which I have set at 4096/8192.

I'm digging your artwork/galleries; so this information is a great little insight into your work!

Quality 10 is probably way overkill and will make it render 10 time slower, as I understand it. Have you tried lower values? I seldom need a quality over 2 for portraits. If small areas are not totally converged, it is fast to spot render them to a file and patch the original image, rather than wait for the whole image to render at a super high quality.
