Did you reinstall the Lincoln Tshirt product?
Did you reset the default dForce simulation settings ( Simulation Settings Tab)?
Are the Simulation Surface settings looking like the 2'nd image I posted? ( It means that Lincoln Tshirt uses the default DazStudio Surface Simulation settings, wich is OK)
Check and update your graphic card drivers, it could help!
I did uninstall then re-downloaded and installed Lincoln's clothes.
I was thinking I'd test another clothing set entirely before re-trying the newly-installed Lincoln shirt on the default Micheal 8 just in case the character was the problem, and upon hitting simulate, I got the error message that I hadn't set it up properly prior to simulation.
So I tried two other, different sets by different vendors and both of those gave me errors, too.
All of these little problems started when I updated Daz a week or two ago.
Did you update your graphics card driver to be compliant with the minimum required version for DS 4.20?
I have the newest Alienware, so I hope everything is up to date, lol. But putting it through some updates and health checks with the SupportAssist tool.
Did you seledt your graphisc card as the simulation device in Daz Studio?
Never had to do that before, but will check ...
Do not "hope", check and update! Buying recent new hardware doesn't mean that the drivers are up to date. And do not install a Gaming driver!
And here is the V shape morph I made for the Lincoln shirt's front collar, just extract the zip file to your Daz3d content folder.
Mine says NVIDIA CUDA GeForce RTX 2060 ... which was working fine before I updated Daz. Do I need to switch something?
And thanks for that morph :)
You must download the last driver for your RTX 2060 and install it: https://www.nvidia.com/Download/driverResults.aspx/187302/en-us
My experience may not be typical. I currently have a GTX 660Ti and an RTX 2070. Until 4.16 both of my cards supported GPU rendering (maybe 2-3 years of joy). With the 4.16 release, there was a change to DAZ Studio requiring a version of the open something or other which made the GTX 660Ti unable to support GPU renders. I vented aimlessly, frustrated that I didn't see it coming, but felt no bettter. My GTX 660Ti became the card for my monitors and the RTX 2070 was dedicated to supporting GPU rendering. Having vowed to be smarter the next time, I carefully 'looked' at the release notes for 4.20. I wouldn't say I 'examined' the release notes as that would require a skill set I do not have. Anyways, I gave it a try and managed to have no GPU support for rendering after the update. The DAZ Studio log file told me I need a video driver of >471.?? and I didn't so I was toast. Again, I didn't see it coming but havn't done the review to see if I even could have. After a week of trying different drivers (yes the most current which is a great line for something...), swapping physical slots, uninstalling and reinstalling, restarting and rebooting, clean installs, running DDU etc etc, someone at nvidia suggested 472.12 (which I don't think even came up in any of my searches) and within a few minutes I was away to the races - at least with my RTX 2070. . . . This may only delay the inevitable, of ungrading everything, but I am happy for now. The point here though is that this is certainly NOT the most current driver. I do think what I am seeing is, that for my setup at least, the video driver must be the same for both cards: this may not be possible for much longer.
So what. I might not be pushing the technology envelope. But for what I am doing, as I toss cards to the curb, I am not seeing coresponding improvements. Maybe it's the bigger, bigger, bigger issue (without the better, better, better). And maybe my 'retrospective' of ten years is not enough. With the relatively recent obsolesence(s), I do not see render quality remarkably better, I do not see render times improved, I do not see a solution to the VRAM memory trap causing fall back to CPU rendering and I do not see a reduction in random crashes when I press the render button.
Perhaps this leads to a turning point; or, perhaps my assessment is all wrong. (What follows is a bunch of undefined qualifiers...) When I first started I think what I had was a mid range PC, perhaps towards the top of the mid range, but it seemed to be more than enough. Sure I wasn't doing animations of multiple characters with fur or anything like that but it was 'good enough'. It would be reasonable to say over time my standards and expectations have changed; but to do the same type of thing today I believe requires much more than a mid range PC. A conclusion might be that, as a hobiest, I am no longer (perhaps never was) the target user for DAZ Studio and as such am being left behind. (This is not intended to start the 'It's free...' discussion as this is more about hardware I think.)
