I am sure this was answered somewhere in the past, but I am not finding it. Several Daz3D versions ago, I lost the ability to render just using my CUDA (CPU off). Before the flame bombs start going, I have an ancient GeForce GTX-760 card. If I only have CUDA turned on, it won't even start processing the image. The only way to get it to render is to run both CPU and CUDA on. Which, for my complicated set, takes about 2 hours plus to render each image. Under General, I have Allow CPU Fallback unchecked but have allow GPU detection and check GPU driver versions checked. Any suggestions on how I can get back to CUDA processing only without CPU?

When Daz renders it will either use GPU or CPU, not both at the same time. In the 2 hour render it is not actually using the GPU at all. If you want proof, open the performance tab on Task Manager and look at the GPU Ram usage and temp.

To get it to render on the GPU you need to get VRAM consumption under what is on the graphics card. To do this you need to ensure that the geometry + material VRAM usage is low enough. There are a number of posts related to how to do this.

Note: It is possible to render using multiple GPU's however the scene's VRAM usage needs to be less than the VRAM on each video card. Hence if you had a 4GB and 8GB video card, to get the scene to render using both, you would need to keep the scene VRAM usage to less than 4GB.

That was a nice long answer, but unfortunately not applicable to my situation. To test this, I created an empty scene with a simple primitive sphere, colored white. I turned CPU rendering off (in the Advanced render tab) and left GPU rendering on. Rendering window popped up and after about 5 seconds closed down and gave me a blank render window. Now, are you trying to tell me that my primitive sphere is exceeding the VRAM usage capacity on the video card? I know this is not so because in the past I have been able to do many renders in GPU, and most of them were quite a bit more complex than a primitive sphere, so I don't know what has changed so that I cannot do it any more.

If you can't render a sphere, it's not a VRAM issue. My only other guess is that your nVidia drivers are out of date.

I think Nvidia stopped supporting iray for older cards. You probably need an older version of Daz Studio and gpu drivers.
Maybe try asking in Daz forums...

Question related to scripts in Daz-

If I wanted to update the scripts for Futalicious Full Monty BBQ to work with Genesis 8.1, would that just be a matter of opening the scripts in a text editor and replacing certain names with other names (such as changing the "Torso" surface to "Body"), or is it more involved than that?

I think GTX760 was officially dropped from something like 4.14 onward.

Honestly, it would be faster for you to just try it and see... and make sure you report the results back here. For Science!

Sadly it seems the scripts are encrypted and not readable in a text editor. Looks like we'll just have to wait for an update

Olympia 7 for O8 seems to have seams (on my config) around the upper thighs and the arms near the armpit (jpg compression makes the seams a bit difficult to see). Is there a way to fix this or am I fucked?

Ok, here is one of the wildest things I have seen yet. I have weird artifacts that appear on my G8F actor's forehead, but only when the hairstyle Trish Hair G8F is turned on. Here's what it looks like:

If I hide the hairstyle, the artifacts go away. Anyone have something like this happen before? Am I screwed and just need to move on to a different hairstyle?

I get this all the time. It's the hair cap poking through. I just shrink the hair's head size dial by tiny increments until it's gone.

Too lazy (and impatient) to wait for a response. Since it's for a new character and nothing was set in stone, I just changed hairstyles. Playing the Sims taught me you can never have too many hairstyles in your inventory.

I can think of two possibilities.
1. Transmitted and SSS colors are not the same for all skin surfaces.
Select all skin surfaces and see if there is a "<?>" in Transmitted and/or SSS color tab
2. You have spectral rendering enabled
For spectral rendering Transmitted color has to be "0.99 0.99 0.99" But you have to edit other shader parameters to make it look good.

I have spectral rendering on, searched for Spectral rendering seams on google (thank you for the keywords!) and a post (

bottom most) mentioned that using a low measurement distance helps. I'm currently testing if it helps.

Edit: Nothing worked except turning off spectral rendering. I did a render with the same exact settings only with changing the SR off and the seams are gone. Shame really, I prefer the way faithful 1964 looks - though when I compared the images the difference is quite small and probably not worth the extra render time...

Thank you for the help.

Hey , would anyone happen to know how to convert Olympia 6 to G3 or G8 ?
I have a gen2 character in my game that is based on Olympia 6, and I need to convert her to G3 or G8 . I can transfer the morph easily, but I can't find a way to convert the materials, as there are no Legacy UV for olympia 6...

Edit nevermind I found a way.

Is there a good way to fix clipping in dforce clothing? Could I grab the vertices that are causing problems and edit the coordinates or something?

Mesh Grabber is your friend for almost every type of clipping. I've even used it to move hair clipping through ears, and to move laces to appear to be falling downward as if affected by gravity.

Not sure this is the right place to ask..

Are there any inverted nipple assets out there for Daz?

Headlights has a ton of morphs for nipples, there's probably something there

I just cloned my original drive for a starting point just incase I screw up things AGAIN!! and am now using the clone as the main drive. I noticed that there is now 3 "My DAZ Library" listed in the content 2 of which seem to path out to different areas of the drive, and are also empty ( nothing at all in them ) just an empty directory at two different locations. Is that something that may be normal and also just be ignored. I think that I had that once before and deleted the empty listings from content and that was one of the times I screwed things up pretty good..... Just wondering.. Daz also saw a hardware or system change and I had to re-authenticate again but that just seems to happen now and then I have also noticed.
