Open PME Preferences directly from a menu

Outcome

Put PME Preferences one action away from the workflow you are shaping. The command opens Blender Preferences and selects PME by its module identifier.

bpy.ops.preferences.addon_show(module="pie_menu_editor")

Steps

1. Create a Command item in a Pie Menu, Regular Menu, Popup Dialog, or Panel Group.
2. Name it something unmistakable, such as PME Preferences.
3. Paste the command above into the item’s Command field.
4. Invoke the item and confirm that Blender Preferences opens with Pie Menu Editor selected.
5. Keep it in an authoring or maintenance menu, away from frequently used modelling actions.

The images are from a 2024 source setup, so newer Blender versions may look different. PME 2.1 still uses the module id pie_menu_editor.

Why use this instead of a small preferences popup?

Use it when you need to compare several PME preferences, resize the settings window, or adjust a menu while looking at its surrounding Blender configuration. The command is a direct route to the original settings.

Pitfalls

• The command depends on PME being installed and enabled under the module id pie_menu_editor.
• Save preference changes through Blender’s normal preference controls.
• A custom command can only be as portable as the Blender version and extension installation that provide its operator. Test it after moving to a new Blender installation.
• Read and understand commands from external posts before adding them to an authoring menu.
