[8.3.0] Memory problem with Substance Painter

[Guest]

Hello,

I'm currently experiencing an issue with Substance Painter that is causing a "CefSharp.BrowserSubprocess.exe - Application Error" error with the exception "Unknown software exception (0xe0000008) occurred in the application at location 0x00002FF93855FDEC", when using two instances of Substance Painter at the same time after few minutes.

After checking the Windows Event Viewer, I also noticed warnings from NVIDIA OpenGL Driver indicating that the NVIDIA OpenGL driver encountered a memory error.

The NVIDIA OpenGL driver has encountered
an out of memory error. This application might
behave inconsistently and fail.
(stop logging every single event of this type
because there are too many)
(pid=9748 adobe substance 3d painter.exe 64bit)

I'm on Windows 11 (22H1), I have an NVIDIA RTX A4500 graphics card with 16GB of DDR4. (Yes, Windows, and Drivers are updated)
I am cloud computing and do not have access to the components or the ability to increase memory.

I am aware that this can be a problem with Substance Painter, but I would like to know if you have any suggestions or tips to solve this problem.
Can the Substance Painter configuration be adjusted to reduce graphics memory consumption?
Or any other solutions?

Thank you in advance for your help.

Hi @Deleted User,

Thanks for the question.

Depending on the hardware and depending on the projects, running multiple Substance 3D Painter's instances can obviously bring some issues.

If you want to try to reduce the VRAM consumption:

While creating a project, make sure your Document Resolution is 1024 or below. I would advise to avoid the UV Tile workflow. You can deactivate the Temporal Anti-Aliasing from the camera's parameters and you can lower the shader's quality.

I can't guarantee you it will solve your issues, but it worths a try.

Best regards,
