Renders finish too quick and surfaces appear pixelated

hi,
When i first started using Daz, when I rendered my characters it would take several minutes, and the rendered images were of great qulity.
I think a configuration or parameter got messed up somewhere along the way , now when I render characters, it seems to finish in a matter of seconds and the character's skin appear pixelated.
Coule anyone venture a guess as to what's going wrong. Thanks

First, Go to the Render Tab > Editor > and click on Default
It sound like you have somehow made changes to your Render Settings. As nemesis10 suggested, you can easily reset the defaults.
However, you changed the settings in the first place, so it may be useful for you to know how you did that. For example, did you install the Render Throttle product? If so, it would be best if you went through the documentation and made sure you understand how it works. (I do not have it, so I can't be specific.) I understand there are presets for rendering low quality and high quality, to help with one's workflow.
There are any number of products that change Render Settings. If you have an HDRI lighting product, double-clicking on a preset might change Progressing Rendering settings, too. (A personal pet peeve of mine!) And if you're trying to use a specific HDRI for the scene, resetting to the defaults will remove that HDRI.
The settings that are most likely to affect the length of time your scene renders are under the Progressive Rendering settings. The attached image is a screenshot I did for something else, but shows the parameters. The three which are most likely to stop a render short are Max Samples, default of 5000; and Max Time (secs), default of 7200; and Rendering Converged Ratio, default of 95%.
If you set Rendering Quality Enable to Off, the Rendering Converged Ratio is no longer in play. You can then control the length of the render by either Max Time, or Max Samples, whichever is reached soonest. I personally set Max Time to 0 and effectively turn off the setting. (Doesn't work for other settings, though.) Then I control the render length by Max Samples alone.
Anyway, good luck. I hope you find what made the changes, so you'll know when you have to check/redo the render settings in the future.
Guys, thaks for the response... but I followed your instructions.. and I set my rendering parameters to default, my settings on the two panels you posted match yours... and I still have the same issue... I render my figure and it finishes up in 16 seconds and my figure looks half baked.
Is there some setting in the figure itself that could cause this? Or anything else you can think of??
Thanks!
The image I posted has a popup menu that is covering the values for Max Samples and Max Time. I did list the defaults as 5000 and 7200 respectively in my comment, but if you went solely by the image...? Is it possible you entered 50 and 72? (I'm thinking not, but I still have to ask.)
I don't know of any settings that affect the length and quality of the renders other than those in Render Settings. There are numerous presets available, but as far as I know, they only modify the parameter you can find in the Render Settings->Editor, (change values, add or replace images, etc.) I'm no expert, though. Perhaps one of the mods can verify that.
I'm thinking the next step would be for you take screenshots of your settings and let us take a look. Maybe one of us will spot the culprit, if we can see your actual settings.
Thanks, I'll send screenshots tonight...
I tried updating my nvidia drivers and I updated Daz itself, and this didnt fix the issue...
Im thining about reinstalling daz... if i reinstalled daz would I also need to reinstall all my assets ? Thanks
I believe if you set the maximum time to 0 the render will keep going for as long as it takes to reach the resolution (max samples) you have it set to.

This works if Quality is set to Off. Otherwise, the software still tries to reach convergence.
@heisdave, Does this happen with any and every scene? Have you only tested this with the one scene? Or only tested with scenes you'd already created and saved? Or have you tried putting together a new, simple scene and hit render?
I still want to see those screenshots, but I was wondering, too, about what you're rendering…
Gawd, we need a manual ;)

okay, so i still dont know what the real problem was, but if i turn rendering quality off and set max time to zero, it runs longer and produces higher quality images again... thanks
I'm happy to hear you have a solution, for now. I'm sure there will come a time when you look at your settings and do a palm-slap to the forehead. I know I have, from time to time. It's just difficult to know where to look when you're still learning the basics. And with only a few exceptions, I'm sure, we've all been there.
