Not sure where to post this…
With Blender 5.2 I’m having trouble exporting meshes as .stl files. The export results in an empty file, 84kb. This isn’t true of every file, I open one file and I can export meshes as stl files, but then I open another .blend file and exports no longer work.
With the information provided it’s possible to say with certainty that you have a problem. That’s about it. If you want help, I would suggest providing more information. Screenshots, .blend file, detailed descriptions of every step needed to reproduce the issue, your PC specs and everything else that is relevant to the problem.
