I just bought
Her skin is 8k!
It is the best I have used so far!
Are there any other Daz figures with 8k+ skin?

I actually purchased because of your recommendation here. The picture of skin is not 8K. Only for the torso and legs are the roughness and bump at 8k. Plus there's another interesting looking texture for ? dial ... so presumably these could be used with almost any other existing skin pictures.
I was hoping that the skin images were 8k, oh well.
Hello Catherine, I am not really sure how skin textures are measured I am just going on the assumption that higher resolution would provide better looking skin.
I am also still trying to figure out how to get skin tones to match, so maybe I am at a beginner level in some respects hoping that higher resolutions will give better results.
I am glad I bought Hersilia's figure and it was on a good sale. I have had a 50/50 result so far, it woks well in about 50% of situations which is a good margin comparatively.
It is the first skin that I have ever seen on Daz to go up into the 8k resolutions. So I will support this effort for that alone.
I plan to use it a lot more and try and use it to understand what kind of improvement it has to offer over time.
I guess the bump maps at least get us into the ballpark, so to speak. Bumps are often the weakest part of skin because they look like reptile skin if they are not fine enough. Especially around the neck and knee areas.
I am sorry if my post was misleading, I misled myself I guess. I am still glad I have this skin to try it out and see if it has some genuine benefits.
Basic G8 without anatomy or lashes has 6 material zones, Head, Torso, Arms, Legs, Mouth and Eyes, these usually have 4-5 textures/maps assigned to them => 30 separate graphic files, which at 4096x4096x24bit use 1440MB:s of memory. If they were all 8192x8192x24bit, the memory requirement would be 4 times as much = 5760MB:s.
What does it mean... If the torso texture covers height of around 1.2 meters, at 8192x8192px, every pixel is 0.15x0.15 millimeters (= 0.00577x0.00577 inches)
Back home, so made some measurements with G8F and 4096x4096px textures (1 inch is 25.4 millimeters / 1 millimeter is 0.0394 inches)
Torso, distance between points; 1481mm - 912.7mm = 568mm (2160px)
Torso at 4096x4096px = 0.26mm/px => 3.8px/mm
Head, distance between points; 1699 - 1576 = 123mm (1453px)
Head at 4096x4096px = 0.08mm/px => 11.8px/mm
I can see the point for artistic nudity but if you're going to cover them in clothing... not so much
8K skin textures would be great if only PA's would be more confident on areola, nipple and genital zones, mostly of them are shy to give detail on that zones that I need to do iRay decals from P*rn videos or photos
the name stats SKIN textures...aren't such areas/zones part of the skin?
Based on my measurements, with 8K torso texture you would get about 64 pixels per square millimeter, which is about the area of the square end of a matchstick (at least here it is)...
Nice insights, but G8s have 16 material zones, just many of them use the same materials by default, e.g. arms/fingernails or sclera/iris. But worst case is 16 independent materials. Also, the image may be 24 bit, but in the driver the data structure that represents a pixel is always 32 bits. So the memory impact is even worse than you say.
You'd think so. I use MR resource photos for stronger detailing. There "used to be" a decent collection over at Artstation which didn't require any subscription fees to acquire them.
No problems. But that's why I posted more details, so others reading will know too exactly where the 8k resolutions are coming in.
Yes the bumps/displacements can really make or break any texturing efforts. I'm keeping the set. In the new year am planning to see how they work with my own skin texturing efforts ;-)
Might be hard to market and make it worth it if Daz doesn't allow those promos in the first place.
What a great amount of info here!
I thank you all for contributing to this thread.
I create gay romance images and they are all "non nudity" but the people who love my art like my guys shirtless and preferably in a bathing suit rather than pants or pajamas.
The problem is two fold. Some textures do not have enough skin imperfections and secondly the bumps look like reptile skin especially around the neck, knee and finger areas.
I am not saying this to insult the Daz Models, I LOVE my Daz models, I just would like better skin. In most cases with the right lighting and tweaking the bumps and picking the right figure textures I can pull off my scenes very well in gigantic resolutions.
I would like to see more imperfect realistic skin textures and better bumps.
If skin is too perfect it is not worth purchasing because it lacks realism when rendering large resolutions. One character with imperfections and one with perfect skin they do not match and it is obvious.
This is were Photoshop comes in perhaps some freckles brushes from Ron would help, and some skin brushes moles, scars, freckles, creases, wrinkles and blemishes but then you have to colorize these transparency layers and laying them over the figure can be very complicated. I prefer assembling scenes rather than creating them from scratch.
This is why I buy them already made.
I can pretty much tell from the promo images if I want the skin, they usually always show an up close of the face and neck.
Skin from photos are often a good bet.
Sometimes I will buy skin mainly for the included hair attachments.
Curious, what size image do you generally render to?
If we click near the bottom of the typing box there's a red arrow that shows up, click on that and then the quote [hopefully] gets ironed out right. {sigh, it'll be nice when this whole forum software has been twigged just so}
Okay, I've made note. I have an idea concerning making more realistic skins however how practical it might be or even if indeed it's truly possible remains to be seen. Definitely steps up from beginner stuff lol ... projects for the new year :-)
Does anyone have? or can share? some renders of the 8k bump and or roughness? The promo images are not even close enough to crisp. That would be great.
Maybe most of the world still plays under the bed covers in the dark? Don't worry though. You can get highly detailed weapons right down to the safety switch! Nipples Presenting is always bad. /Eyeroll
That's a handy comparison.
How did you calculate the memory usage? By my math 4.096x4.096 x 3 (Shortcut for 24 bit) = 50.33 MB x 30 = 1.51GB. Am not using MiB.
@Mystery . Is that for sure 100%, that calculations are 32 bit? True on shared maps, though how does DS parse that in it's various stages? Is that been detailed anywhere 100% accurate?
Width (px) x Height (px) x color depth (bits) / 8 (bits) / 1024^2 = MegaBytes
IEC Clarification about MB vs MiB >>>>> https://en.wikipedia.org/wiki/Kilobyte. ; 1024 would supposedly need MiB to be clearly distinguished. Unless I read wrong.
Your original you wrote MB:s, wasn't sure, so had to ask.
Outside marketing purposes, 1024 kilobytes makes 1 Megabyte and 1024 Megabytes make 1 Gigabyte, it has been this way the 30+ years I have been meddling with computers.
The MiB is a new definition that maybe tries to bring the definitions a bit closer to SI standard.
The first time ever I saw KiB and MiB used, was in as DS logfile and at some point had to check what they actually meant.
I have Hagar, which is an excellent character, and have just picked up Zhao, which also contains some 8k textures.
Larger textures can give better details.
It depends on the amount of details put into the texture and the quality of them. It then depends if you're getting resources with jpeg, png or tif. Jpeg are usually 8 bit textures and are also often saved partly compressed; this is going to loose details.
After you get the textures, what's your plan to bring all those details out?
These are both of Hagar, rendered in Blender's Cycles. Was experimenting with a hair plugin I was testing out when I noticed this thread earlier.
A lot this, generally we'd be better off with the 4K textures but in a lossless format like PNG.
I just made a thread if it was possible to get the original PNG files for characters I purchased, because I looked at a good number of those that I have bought and all the JPGs are at a pretty aggressive level of compression - there's very noticeable artifacting in the images. I might have to give Artstation a look.
