My second attempt at 3D rendering. Started to experiment with HDRI, 3-point lighting, and camera depth-of-field.

I don't like how she looks so unnatural, but I can't really put a finger on what I need to change. Suggestions and recommendations very welcome!

"Wistful Regret", take 2.

Played around with eyes, mouth and neck position based on the really helpful suggestions by Willibrord and OldMoonSong. I think it's looking much better now! :)

by what margin does Ram effect renders i have 16gb Ram im running an i7 and an RTX 2070 would a Ram upgrade make a difference in render speed
1. With more available RAM you you will get better performance from DAZ in all aspects, for example in the scene window where you do most of the work with poses, textures, props, hair and clothes pairing.

2. OptiX Prime Acceleration for my opinion saves 20-25% of rending time (on my 3950X 16 cores Ryzen 64Gb RAM). Turn it on in Render Settings tab:

For i7 (4 or 8 cores) and 16 Gb RAM effect of OptiX should be less visible, but if you are not against to give DAZ all your available RAM (It will consume all, believe!), you can try.

3. With more available RAM your can render on CPU almost any complex scene. Yes, it is slower, then on GPU, but you will not have any real limitation for textures or models with GPU RAM 'overload' issue. Don't forget to include de-noising features, if you render on CPU, your will have a very good grain dumping even on 600-800 iterations with ~20-30% image official 'conversion':

thank you i tend to use only HD characters and with some of the newer hairs my PC has a meltdown and becomes unresponsive this might help

I get the feeling that the character's fingernails, hands and forearms have lost an important light-scattering effect? It just feels like they are too pale against the tone of the model's main body. Could this be an side effect of the LIE-preset tattoo?
was just a quick render to respond to a challenge, heavy desnoising is probably the reason.

By no means a nag, it's just that the eye clings to this effect: areas of skin that have more or less the same lighting look completely different, with the hands looking more like plastic. Although normally, the character's hands are usually more reddish in colour, as the capillaries are closer to the skin and there are no fatty layers in these areas. Well, unless the hands are totally frozen. ;)

I'd look specifically at the skin shaders, maybe an overlay or some of the SSS tint or Translucency parameters fell out somewhere.

What kind of rendering times do you get with your CPU? I exclusively render on GPU, despite having a decent CPU (i9 9900K) and plenty of RAM. If it doesn't take ages compared to my 3070 I might consider it for some scenes. I have how NVidia reduced the VRAM on the newer cards, my 2080ti had a much nicer amount of VRAM available, 8GB is quite easy to fill with a simple scene.

Empty scene with single HD model and some props is about 30-40 min on CPU. Example:
AliceSmile.jpg

Complex environment with four HD models and a lot of props is about 2,5 hours on CPU. Example:

d20 nightT 8.jpg

Usually I render in 1920x1080 in landscape view and 3413x1920 in portrait view.
Example images done with no post-work denoising, only DAZ in-render denoising.

Since I'm rendering in the background anyway, under Wine on Linux, I'm quite happy with this approach (as for TOP utiliy info, DAZ uses about 14-15 cores out of 16 and 50-60% of RAM).
The computer is a 3950X Ryzen 16 core (no boost), 64Gb RAM.

What settings do you use to render? Do you keep quality convergence on, or do you select a certain number of iterations?
I feel like CPU is not the way to go for me then, with my GPU a single HD model with some props won't take more than 5-10 minutes.
With four models the issue becomes whether it fits in the VRAM sadly.

I'm under no illusions: 16 cores (32 threads) of the most advanced CPU will never keep up with the ~2500 stream processors of 2070x, for example.

The main advantage of the CPU is the 'time free' noise reduction and the ability to pop virtually any scene of arbitrary complexity into RAM.

I don't focus on conversion ratio, in a noise reduction rendering situation it doesn't say anything anyway. On some scenes even 10000 iterations show 40-50% in this parameter.

That's why I'm more focused on the number of iterations itself. If the scene is well lit, 600-800 iterations are usually enough, if the composition has a lot of mirrored surfaces and dark corners, then it's better to wait until 2000-3000 iterations. After that, there is no special growth in quality, and it is not visible to the eye, to be honest.

Sorry, what do you mean by time free noise reduction?

I agree on the convergence, it's completely arbitrary and in many cases not necessary to reach 100%.

I generally just render at a higher resolution (2560x1440) and then at 2000 iterations. For the renders I use for my games I then downsize to 1920x1080 which also further increases quality

any better?
tweaked the SSS but the skin itself has blotches and blemishes that are exaggerated in the harsh light so only so much I can do with this set up without affecting the whole scene.
