Black screen

I have the same issue. Opening Substance 3D Stager for the first time, opening a new project: I have a blank viewport and cannot exit the application.

System details:

• Windows
• CPU: Intel Core Ultra 7 255HX
• RAM: 32 GB
• GPU: NVIDIA RTX PRO 3000 Blackwell Generation Laptop GPU
• NVIDIA driver: 591.86
• Windows user profile path: C:\Users\...é

The log shows that the GPU is detected correctly and that Direct3D, OpenGL, Vulkan, and the ray-tracing pipeline initialize successfully. The failure happens when Stager tries to access:

C:\Users\...é\AppData\Roaming\Adobe Substance 3D Stager\RTECache

The relevant errors are:

• GetDiskFreeSpaceExA() ... failed, error=0x00000003
• Engine scratch space of 0 bytes less than minimum of 2 GB
• Failed to create the scratch Bundle in textures.aeroresource
• Engine could not initialize the texture scratch VFS
• FAILED TO START UP THE RTE ENGINE

The RTECache folder exists and is empty. I also renamed the entire preferences folder from:

Adobe Substance 3D Stager

to:

Adobe Substance 3D Stager.old

Stager successfully created a fresh preferences folder and a new RTECache, but the same error still occurred.

Because the Windows profile path contains the accented character é, I suspect there may be a path-handling issue in the rendering engine or its filesystem component.

Could you confirm whether accented or non-ASCII characters in the Windows user profile path are supported, and whether there is a workaround that allows the render cache or scratch folder to be redirected to another path?

The application also produces UI errors after the render-engine startup failure and cannot be closed normally without ending the process in Task Manager. Loading an example file takes forever as it is stuck in loading.

Thank you for any suggestions.

I am having the same issue…. Everything was working fine but now when I open the project I have the black screen. There are multiple links and artwork in the file. I deleted the cache + folders, cleared logs and still nothing….. I want to note that I am using a Mac Studio M3 Ultra computer so as Apple thought it would be a good idea to remove the powerful GPUs and give us some little integrated garbage chip I am not sure how to fix this. Any ideas?

To confirm, have you seen this help article and tried the solutions there:
https://substance3d.adobe.com/documentation/sg/stager-viewport-is-blank-225969628.html

The blank viewport occurs when the app isn't able to initialize the rendering engine, which is almost always because of the graphics card configuration issue.  You need to check both the Windows settings and the NVIDIA control panel settings if that's installed as they can conflict with their settings.

Hello, can you tell us more about your system? Can you try the previous version to try?
