Author Topic: Artifacts all over mesh when opening up to date version.  (Read 3962 times)

I've been getting this ever since Painter changed to a GPU view-port (I believe that was the change?)
And make it impossible to use. All masks get artifacts in them and as you can see, makes the resulting textures unusable.

It seems to coincide with not having the latest match up with both Painter version and GPU software version.
So i can temporarily fix it by updating the GPU or Painter.
But this seems to happen at least once every few days, and it's incredibly frustrating trying to jump in to finish of some textures and export quickly only to find it's yet again completely broken and i have to go and download another driver. (May be fine for yall folk overseas but internet in Australia is trash at best)

Is this a bug that can be fixed? or do i have to keep fixing it whenever it breaks?

Broken textures.


What it should look like.

Having the same or similar issue with the latest build and the previous, sometimes it looks ok in the viewport but when I export the textures there a strange square artifact appears on different sections of a model. There are times it has done it in the viewport. I've had issues if I use the stencil tool, it creates weird pixel/squares where I just painted and won't disappear sometimes.

The latest version is up to date plus just updated the latest Nvidia drivers.

Can you try to downgrade your GPU drivers to version 388.x and try again ?

Had the same issue, downgrading to the 388 NVidia driver solved the problem.

I have the exact same problem. It is incredibly frustrating. Switching back and forth between resolutions can sometimes fix it if you're lucky. The second problem i once had, with the top right quadrant of the UV map having a darker shade than the other 3 quadrants. But the most persistent problem is the artifacts all over the mesh, usually from only a few select layers.

I'm on Nvidia 416.xx or something around there, and want to also switch back drivers - what's the best way to do this?

Thank you

EDIT: nevermind, found the relevant info in a sticky at the top of this forum.

 I still have this problem in 2018.3, mainly when switching frmo 2k to 4k resolution or using the poly fill tool. Does no one else have this?

It seems to disappear when i disable all Normals channels in the project. Or switch from 4k to 2k, but then other blocky artifacts appear all over, unrelated to the normals. Saving and restarting SP fixes it.

Up to date shader btw.

Nvidia 411.70.

Cheers

EDIT -  after another test and restarting, having the normal map channels ON upon loading - no errors. So really not sure what is causing all this.

EDIT -  further testing reveals it to be normal channels in general. Switching them off on layers makes the artifacts disappear.

Can you try the following workaround ?

  • Go in the Settings (Edit > Settings)
  • In the General section scroll to "Sparse Virtual Textures"
  • Disable the setting "Hardware support acceleration"
  • Save and restart Substance Painter

I'm having the same issue in version 2019.2.0. I have a Quadro P3000 using driver 26.21.14.4128. I was having this issue a few weeks ago and I updated the driver and it seemed to fix the issue, now its back. I've tried re-setting file size with no luck. Please see image.

Hi,

Is this a big project?

Could you try to clear out a bit more space on your disk C? Both your temp cache and svt cache are stored there, and if your project is rather hefty, it can go up pretty quickly during a session in Painter.

You could also try to reinstall the driver if the above does not work.

Also, how many monitors do you have? Are you running Substance Painter on the main one?
