The "3D VIEW" is showing a preview of the entire Substance window instead of the actual 3d view. I have tried Scene > Reset, disabling post processing, reinstalling, rebooting. Nothing causes the 3d view to show anything but a scaled, upside down view of the whole window. Attachments show what I'm seeing.
How do I fix this?
This is strange indeed!
Please provide me with Designer's log file (Help > Export log file), so I can check a few details about your system and Designer's activity.
Thank you for providing this log file, and for your patience.
The log lists shader compilation errors occurring when initialising the 3D view rendering using OpenGL. This can occur on some system such as MacBook Pro laptops where the GPU does not support enough samplers to compile the default Adobe Standard Material shader. In those cases, Designer should fall back to the PBR Metallic Roughness shader and initialise the 3D View correctly.
However, it appears this is not the case on your system, and the 3D View displays whatever is in the GPU's frame buffer after the errors occur, which happens to be Designer's main window (which is also rendered using OpenGL).
In the 3D View panel, go to Materials > Default > PBR Metallic Roughness > Parallax Displacement, then go to Scene > Save Current Scene State as Default.
Close the 3D View panel and, in the main menu, go to Windows > New 3D View and check that the 3D View panel correctly initializes the rendering of a 3D scene.
Feel free to let me know about the results!
That sounded promising but did not fix the issue. I tried restarting the app completely after making the change as well, along with trying a few other materials. Any other things to try?
Thank you for following up with an update, I am glad the issue is solved!
That the GPU was external is a very interesting detail! This is very likely connected to a driver issue and the 3D View defaulting back to whatever was in the framebuffer.
I will keep that detail in mind if any other report similar to yours comes up. Thank you for your help!
