I am rendering in 2D only. I am looking at the quality of the example shown https://www.daz3d.com/compact-studio-room.
My quality is very much below this. Would I be able to get to that quality only using DAZ3D or do I also need to use other programs as well.

You would of course get that quality just using Daz 3D and there are probably also cameras included in the set to
get any of the promotion images angels.
Thank you. I just wanted to make sure i was not wasting my time learnng how to do this.
What exactly do you mean when you say that you are only rendering in 2D? All renders produce 2D images, but DAZ Studio, with the exception of 2D images used as backdrops or for image-based lighting, uses 3D assets to produce renders. If you mean you want to produce composite images using only 2D assets, then you really don't need DAZ Studio for that. Insofar as the quality of the renders produced using 3D assets in DAZ Studio, yes the results that you are referring to are achievable. In fact, I would be surprised if those promo images were not produced in DAZ Studio.
Perhaps you could explain exactly what it is that you are currently doing, and what you wish to do.
Sure.
Here is my render. You can see the quality is below that in the example.
You can see the quality of my render is not the same as that in the example Compare my faucet which is grainy
vs their faucet which is nice and clear.
That is a common problem that users encounter using the Iray render engine. Assuming that you allowed the render to complete, then you may wish to adjust your render settings. There are three things that will end a render prematurely: the maximum number of iterations specified, the maximum convergence specied and the time. You need to adjust your settings to allow for more iterations in order to reduce the graininess that you are seeing. By the looks of what you posted you are well on the way to achieving what you want. It just needs to finish. One other trick some use to avoid having to increase render times is to set the canvas size much larger than what you want, then reduce the resulting render to what you want in an image editing program, which reduces the graininess.
According to this video. Lights can effect the quality of your render. Is that true are their any addons that you suggest i get to improve the renders?
In the progressive rendering tab. What should my setting be set at?
what for example should i set my rending quality too?
the converged ratio should be at 100%?
Lighting definitely affects the quality of your render. Proper lighting sets the mood for your render, it makes the viewer feel whatever emotion you want them to feel; happy, serious, fear, etc. I don't recommend any addons, personally. Those things are useful, but most of them are things you can do on your own for free, plus you'll learn more. Here's a good tutorial on using emissives for lighting.
For me, the default settings are good for most of my renders.
Converged ratio is Iray's comparison of what it currently has to what the "perfect" picture is supposed to be. In theory, it should never be able to reach 100%, it can always get a little closer to being perfect. In practice, the render will stop eventually, even if you set it at 100%. You can ignore it by turning Rendering Quality Enable off.
Max Samples- a sample is just Iray making an update to the image, improving it little by little each time. If 5000 isn't enough for you, you can certainly raise it.
Max time - the default 7200 seconds equals 2 hours I believe, so you can increase it if you need more time.
If I do change anything, its usually increasing max time. When I was using a GTX 460 1Gb card, most of my renders finished in 2-3 hours or less. If it still has grain after that, I probably set something up wrong. Just remember, as long as you learn from your mistakes you're not wasting your time.
Definitely not 100% ... unless you want to wait forever. :)
Convergence works like this...
What the Render Quality setting does is tell Studio how precisely the two passes need to be compared. I think of it like "How many pixels of the image are sampled to decide the convergence ratio?"
For the settings, for draft renders I typically use something like this...
For final renders I'll go with these values:
I've seen people talking about very high render qualities, but in my opinion it tends to be overboard. 3 has worked well enough for my purposes. Your experience may vary of course. :)
Absolutely. People keep cranking up the rendering settings when they don't even have a decent scene to start with. Chanansiegel, your composition (placing people, props, clothing, etc), camera work, textures, and lighting are the basics of a good scene. The render settings just tell your graphics card (or CPU) how much time to spend on the scene. Think of it this way; if a person takes bad pictures with their camera, buying more expensive film won't help.
As far as your picture above, I'd say there's too much light. It looks like a hospital room or something. I'd remove some of the lights, so there are some shadows in the scene. It looks unnatural without shadows.
what i can tell is, your render doesnt has shadow in it...so it looks flat...
try to get some lights in it and set it so there are shadow to every props
