render quality

I'm still new to Daz Studio and I wonder if I'm doing something wrong with my renders. The render time is very short and the quality doesn't look very satisfying. The images look kind of unfinished to me. I'm using the default settings I found in several posts

What is in your scene? Just the figure, with its clothes and hair and wings?
If you are doing an Iray render, increase your iterations, time, and convergenge...I typically start at 15000, 57600, and 100% respectively....
Frankly, if you just blindly use someone else's settings you'll never understand what impact each of the settings has. Also, some images require different settings than others. Thirdly, your specific GPU will influence some of the values that you use so that your renders are satifcatory to you.
For instance, I never use settings like 15000, 57600, and 100%, yet I am satisfied with my renders. I also typically render at sizes of 2000x3000 or 4000 x 6000 with the ocassional 1080p thrown in. Feel free to look at my gallery. No one has said the images don't look finished. Most of these use the default Daz settings
Realistically, lighting will dominate the result you get for any value of settings. More light will tend to require less iterations for a given image.
You can't set the number of iterations, only the number when Iray will force a stop to it. Same with time and convergence ratio.
Fastbike is right -- Your scenes have unique qualities, just like everyone's, so your settings need to be unique too. Your sample clearly shows unconverged pixels, so if the render is finishing very quickly, it's possible your default settings somehow got changed. First thing to do is hit the Defaults button, which is right under the Render button in the Render tab.
The way to improve this kind of quality is not to pitch in overly high numbers for the stop-at values, none of which are coming into play for you anyway. Tell Iray you want it to do a better job with converging pixels. This is what the Render Quality setting is for. A value of 1 is the default. Set it to 2, and see how that improves things. If you need more, try 4, and so on. Keep doubling the value. For every doubling, render time will of course increase by about the same rate.
Hi,
Hope you dont mind me borrowing the thread and adding some question since its along the same topic.
a) Quality at 1, 2000 iterations, VS Quality at 2, 1000 iterations. These 2 renders looks the same to me. I notice that the Quality setting is more a multiplier than actual 'quality'. Hope someone can confirm if this observation is correct. (I manually stop the render to observe the difference)
b) This one is pure opinion, I could be totally wrong (in fact I want it to be). But I always use the first 100-200 iterations as a guideline to how the final render will be in terms of how bright the lights are. Yes, the grains will clear up, metal get more shiny after 10k, but overall lighting can be observed in the early 100's. Never had a vastly different experience unless its some super dark scenes. Just want to hear how you experts get a 'feel' that things will look good and let it run over night.
@Ruri
The Quality setting does tend to multiply time, but is a quality setting. The difference in quality may not be visible. Quality changes the internal criteria for the definition of convergence. Don't confuse this with the convergence % criteria you can change.
You are correct about the overal lighting, you will be able to tell if the lighting is what you want within a few iterations. Let me ask you a question. Do you often run for more than 10K iterations? If so, what do you think that gives you? If you have complex scenes with minimal lighting, I can see lots of iterations, but otherwise??
