Using DAZ Studio 4.7. When I open a previously saved scene, the skin textures on my models are messed up. Sometimes it looks as if random textures or shadows have been "tattooed" onto their skin. This only appears to be happening with scene files I've saved and then re-opened. It also causes error messages during rendering. Closing and re-opening Studio sometimes helps, and sometimes makes it even worse.
(I'm pretty new to the program, so please walk me through any suggestions you may have.)

I notice from your screen shot that you seem to have two models or characters open in the scene (Girl 1 and Girl 2). Are these two copies of the same figure? Since they are both set to be visible in the viewport and I can see only one, are they superimposed? If there are two instances of the same model in the same pose occupying the same place in the scene, that might be the problem. What happens if you turn off visibility for one?
If I'm misinterpreting what I'm seeing in your screen shot and that is not the issue, then you could look at the log file (found under Help-troubleshooting) and scroll to the bottom of that file immediately after loading the scene and look for error messages.
The second model is off screen. I zoomed in on one to show the issue. The other is not showing any texture problems. The one *not* showing any problems is the default Genesis 2 Female.
The model pictured above, however, is a Genesis 2 Female using the "Victoria 6 string bikini" and "Day at the beach body form". I may not be understanding this correctly, but is the basic Genesis 2 not compatible with these things? Taking off the bikini doesn't help, but I don't know how to remove the body form or "Bree" makeup, etc, to test if the problem goes away.
Here are the things that jumped out at me in the log file...
I've just noticed that the textures showing on her are eye textures that have been stretched out and applied to her skin! Not sure what stupid thing I've done to cause this, exactly... But even if it is my error, maybe someone can tell me what I've done wrong, and how to remove these textures?
There are only two ways that I'm aware of to remove textures once they have been applied. One, if the textures are newly loaded, is to use the undo function under edit. If you have made other changes to the scene since loading the textures, you would need to undue each in turn until you reached the point where you had loaded the textures. In your case, since it is a saved scene, this option isn't available to you anyway. The second option is to simply load new textures, which will essentially overwrite or replace the existing textures. I am unaware of anyway to simply remove the textures from the scene as you would other content found listed in the scene under the content tab.
The log file certainly indicates a problem in loading the texture files, although it doesn't tell me why. I don't think it is a compatibility issue, and if it were usually that means the content simply would not load at all. Something else has obviously gone awry. It is not out of the realm of possibility that the scene file itself has become corrupted.
BTW, is this happening with all your saved scenes, or just some? If you create a new scene, save it, and then close it and re-open it, will it be corrupted, too? If you create a new scene and render it without closing the scene, does it render correctly without errors?
As SixDs says, for some reason the Bree textures are not all loading. Try reapplying the Bree textures onto your model (in the Content Library tab go to People > Genesis 2 Female > Materials > Bree All). Then resave the scene.
The "Day at the Beach" shape looks like it merely increases the Breasts Size parameter. You can see this by going into the Parameters tab and clicking on the Currently Used option. But this will have nothing to do with your problem.
I've played around a little bit, and this is now happening as soon as I load any piece of clothing into any scene. Some of my animations have taken hours, so I'm hoping I can do something to save them... It only seems to be worsening. I've tried reinstalling them (clothing) with no luck. It also seems to be having a hard time finding any files in my content directory. It says "searching" and just keeps going until I close out and open DAZ again. Bizarre.
Can you post your computer specs this is something I've come across in the past due to lack of memory.
To completely remove the textures from a figure select the figure and then select all the surfaces in the surfaces tab then in the Shader presets folder you should find the DS default shader apply that and it should clean out the textures and any shader settings.
No need. DAZ just confirmed a "memory error", and needed to close. Seems you hit the nail on the head, there, Scorpio. I was afraid of something like that. Any way to lower the texture quality, or other settings that will help it run better on my crap system?
I was afraid of something like this. The problem may have nothing to do with DAZ Studio or the content, but may be hardware-related. There are two things you need to do ASAP, and, unfortunately, they are going to mean a little work on your part, and a whole lot of time on your computer's part. During the process you will not be able to use the computer. These measures will either determine the problem or ensure the PC is functioning as it should.
Step 1: Download a copy of Memtest 86+ from http://www.memtest.org/#downiso You want to select Download - Pre-Compiled Bootable ISO (.zip) If you are not familiar with this software, don't worry, it is perfectly safe.
If you don't know about ISO files, they are disk images and your operating system should have the ability to create bootable media from them. You'll need a blank CD or DVD or USB thumbdrive to create the boot disk. Once you have that done, make certain the BIOS is set to boot from that drive first, insert the disk, then reboot the computer. The computer should then boot from the removable media and Memtest will start. You don't need to do anything, just let it run. Depending on the amount of memory you have installed, and the speed of your system, it make take some time (an hour or more). The program will run indefinitely until you exit. If it seems to be passing the tests without errors, let it complete at least one full pass (a series of tests) before you abort. If your memory is fine, you should get 0 errors. If you start getting errors at any point, you might as well abort - you have memory problems. Either way, close Memtest, remove the bootable media and reboot the system to Windows. Then, report back here with the results for further instructions.
Thanks SixDs, I will try that program, and post the results here as soon as it's done. I was thinking more along the lines of my crappy graphics card being low on memory, not something like RAM problems, but I'm willing to test everything. I need to be able to use DAZ for work, so I appreciate the help.
Edit: No errors found.
An update on the issue:
I managed to load a scene without issue, after sliding "Texture Resources" all the way toward "Performance", and lowering the mesh resolution of the model to "base", then saving and reloading. I was also able to render a complex animation by switching to OpenGL (from 3Delight)
So now my renders look like they were drawn by a small child, and I'm not 100% that it's a total fix. These settings still didn't help one of my scenes, either.
I'm using a Dual Core 3.6 x 3.6 ghz, 4 gigs of DDR3, and integrated graphics. XP 32. (I fear change?) Any ideas are appreciated.
The integrated graphics is definitely a problem. 4 Gigs of ram is a little light for large or complex scenes, but that problem is made worse by the onboard graphics which must use the system ram as well. Even a relatively inexpensive graphics card with a Gig of Vram of its own will make a world of difference. Is this a laptop, or a desktop?
I don't like telling people that they need to upgrade, since not everyone has that option, It should be noted, for future reference if nothing else, that nowadays most would consider a quad core processor with at least 8 Gigs of ram to be a minimum for most 3D work.
If you're on 32 bit that's your main problem it only uses a bout 3 gigs of the memory you have. Personally I don't think changing your graphics card will make that much difference.
There are things you can do though.
You have 2 figures loaded, load only 1 and work on 1 at a time save and reboot DS often.
If you want to render more than 1 figure in a scene you might find you need to do it in layers and put them together in photoshop or gimp.
If things are in the background reduce the size of the texture maps.
Learn to do things in postwork.
Keep the lighting simple.
Keep smoothing turned off until render time and as low as possible.
I worked with a 32 bit for ages it actually taught me a lot especially the postwork side - from necessity. I still have a low end system and often have to render in layers if I want more that 3 figures and scenery in an image.
Brandon;
Just a thought, but what size paging file do you have set? The paging file is a portion of your hard disk set aside for use as virtual memory. If you run out of physical memory (RAM), the system will use the virtual memory for any excess. It is slower, but will avoid out-of-memory errors. Typically, the virtual memory would be set to about 1.5x the amount of physical memory you have installed, which in your case would be 1.5 x 4 = 6 GB. If you have the paging file disabled, or set to less than the foregoing, that could explain part of the problems you are having. Even if it is set as described, you could try increasing it, assuming you have sufficient free disk space available, and see if that solves the problem. If that works, it will enable you to complete renders without sacrificing quality, although you should expect renders to take a while to complete.
Thanks for the advice, both of you. I've tried everything above, and it's still not completely cleared up. I'm not going to mess with it, anymore. I got a new, different error along the lines of "textures can't load due to low memory", so it's 100% confirmed. I'm going to save up some money and overhaul everything but my processor. Hopefully, I can squeeze a little more juice out of that, for now.
I think the advertised "minimum requirements" for DAZ might need to be updated, but I won't get into that. It seems like a great program, for the most part.
Anyway, I think it's safe to call this problem "solved". Thanks to everyone who helped.
