Alright, I'll try to explain it without getting confused myself while explaining it lol.

Basically the DAZ render engine when rendering, calculate each pixels and compare them with the original. Depending on the processing power of your computer it can calculate thousands of pixels per Iterations or a few hundred if your processing power is on the low side. Now when the rendering is taking place, it compares the pixels (Position, color, shade etc.) against the original in your viewport. When the rendering engine ''feels'' that a particular pixel is the closest possible to the original it considers it rendered and won't pass over it again. That process is cumulative, the more pixels are considered rendered, the closest the render is converging toward 100% ''perfect''. So when you say that your render is at 15% regardless of the amount of iteration has passed means that the rendering engine considers that 15% of the pixels are ''finished''. Now that doesn't mean that the render will look like crap. When calculating, it passes around on the same pixels multiple times, bringing it ever more closer to being considered ''finished''. So even at 15% if you see that the render is looking good for your purposes, you can stop it and clean it up after into Photoshop, GIMP or an AI Denoiser. For most of the renders people will do, 95% convergence ratio is perfectly acceptable, and sometimes I stop the rendering way before it reaches 98% (Like 50-60% when a render takes forever). I just clean it up afterwards in some other program. If the render is reasonably fast I let it go all the way to 98%.

Hope I wasn't to confusing with the explanation and hope it helps.
Thank you very much! No, it wasn't confusing at all.

My pleasure my friend.

As I thought more on the subject, when you said that you render was at 3000 iterations and only at 10-15% convergence. It tells me either two things. Either you've got a lot going on in your scene or low processing power. There are creative ways to lowering the rendering time. You've got to keep in mind that everything you put in the scene makes the complexity of the rendering process go up. Every character, hair piece, clothes, shiny surfaces (Like shiny skins, latex, mirrors) Furniture, buildings all contribute to the complexity of the rendering process. Also darker scenes take more time than well lit scenes. If you have a lot of stuff loaded into the scene but is not in the frame of your rendering camera, get rid of it. You will see a difference.
this is especially important if you have a slow computer. At that point it becomes imperative that you load stuff only in your shot and leave everything else unloaded. One other thing you can do is render at lower resolutions, like 1080p or 1440p instead of 4K and stretch the image later on using an AI enlarger without loosing much quality. The amount of pixels to calculate increases with higher resolution which increase render time: 1080p is 2,073,600 pixels to calculate, 1440p is 3.7 million pixels to calculate and 4k is 8,294,400 pixels to calculate.

Thank you again!

I have an RTX 4070, so that's okay I think. The resolution I use is usually 2K (1440p) or something around that. It's more about the things in the scene I think. Since I'm making a VN I use rooms or a house as environment.
I'll try to do something about the lighting to see if it helps. (Probably shouldn't start by making night time renders... FUCK!)

Well, dark lit renders can make for compelling storytelling and adds mood to a scene, but it comes with more render time. Such is life lol. Have fun rendering and good luck with your VN my friend!

What do you use for compositing? After Effects? Davinci Resolve? Nuke?

I wish my stuff looked like yours.

Thanks, I really appreciate the help (y). Finding the mixing will be hard :LOL:
P3D katherina HD G8 could be. She has same moles as the girl you looking for. But you can also check other girls from P3Design, creator of Katherine. Authors can pretty often use same skin on different female model. To be honest you don't need prettier girl than this one. This girl is Aria from the same author. Maybe slightly modified with some other his characters for this expressions. I seriously doubt that he made expressions for someone else's model when he has his own. Cause this picture is from P3Design's soft expressions.

Yes, with this expression the model looks really close. I think with some adjustments It can be done.
Thank you very much :)
