While working on Ultraprocessor Ribbon, some team members couldn’t load .blend files and others could despite everyone having set the filesystem/import/blender/blender3_path editor setting. This caused Godot 4.2.2 to complain that the blender scene and any scenes containing blender scenes were invalid or corrupt.

As it turns out, when you set this property using Godot’s file manager and you select the blender executable, Godot automatically sets the path to the folder containing the executable. For example, if Blender is installed at /bin/blender, Godot will set the path to /bin.

However, some on the DemureSoft team had typed the path directly into the text field, setting it to the path including the name of the executable. On other words, they entered the value /bin/blender for the filesystem/import/blender/blender3_path setting. The import issues were resolved after changing the value to /bin and reloading the project.
