Blender’s “Pick Shortest Path” Not Working: Causes, Solutions, and Pro Tips
blender is a powerful 3D tool, but sometimes, features like Pick Shortest Path don’t work as expected. Many users get stuck when trying to select a path between two elements, only to find nothing happens. This can slow down your workflow and create frustration. If you’re struggling with this problem, you’re not alone. Let’s explore why this happens, how to fix it, and how to avoid common mistakes—even if you’re new to Blender.
What Is “pick Shortest Path” In Blender?
The Pick Shortest Path tool allows users to select the shortest route of connected elements (vertices, edges, or faces) between two points. For example, you can select two vertices and Blender will automatically highlight all vertices, edges, or faces between them. This is especially useful for complex models, UV editing, or when you need to quickly select loops.
Common Reasons Why “pick Shortest Path” Is Not Working
Many Blender users report that this feature sometimes fails. Here are the most frequent causes:
| Cause | Effect | How to Identify |
|---|---|---|
| Wrong Selection Mode | Tool doesn’t activate or selects nothing | Check if you’re in Vertex, Edge, or Face mode |
| Non-manifold Geometry | Path can’t be calculated | Use Select → Select All by Trait → Non-manifold |
| Disconnected Mesh Parts | No path exists between selections | Try selecting elements closer together |
| Version Bugs | Unexpected tool behavior | Check your Blender version and changelogs |
| Modifier Interference | Visual mesh differs from edit mesh | Disable modifiers temporarily |
How To Fix “pick Shortest Path” Not Working
If the shortest path tool isn’t working, try these steps:
- Check Selection Mode: Make sure you’re in the correct mode—Vertex, Edge, or Face. The tool only works if both your starting and ending selections are in the same mode.
- Select Only Two Elements: Select just two points (like two vertices or two edges). Selecting more can confuse the tool or cause it to do nothing.
- Inspect Geometry: If your mesh is broken or has non-manifold geometry, Blender may not find a path. Use Mesh → Clean Up → Merge by Distance or Mesh → Clean Up → Delete Loose to fix.
- Disable Modifiers: Temporary disable any modifiers (like Mirror or Subdivision) that might change the geometry in Edit Mode.
- Update Blender: Some bugs with this tool were fixed in newer versions. Make sure you’re using at least Blender 2.90 or later. Updates can fix many tool problems.
- Try a Fresh File: Sometimes, file corruption or complex history causes issues. Open a new Blender project and test Pick Shortest Path on a simple mesh.
Troubleshooting Examples
Let’s look at some real-world scenarios where users hit problems and how they solved them.
Example 1: Wrong Selection Mode
Anna tried to use Pick Shortest Path between two vertices but was in Face Select mode. The tool did nothing. Once she switched to Vertex Select, it worked perfectly.
Example 2: Disconnected Geometry
Jorge selected two edges on different mesh islands. Blender couldn’t find a path. After connecting the islands with a bridge edge, Pick Shortest Path worked as expected.
Example 3: Modifier Confusion
Rita had a Mirror Modifier active. She tried to select between two vertices, but the tool failed. When she disabled the modifier in Edit Mode, the tool worked.

Tips To Use Pick Shortest Path More Effectively
While the tool looks simple, a few tricks can make it more powerful:
- Use with Shift: Holding Shift lets you add to your current selection with more shortest paths.
- Deselect with Ctrl: Hold Ctrl to deselect the shortest path rather than select it.
- UV Editing: Pick Shortest Path works in the UV Editor too—helpful for unwrapping complex shapes.
- Keymap Customization: You can change the shortcut for this tool in Preferences if you use it often.
- Edge Loops: For quick edge loop selection, Pick Shortest Path can sometimes work faster than Alt+Click, especially on messy geometry.
Data: Blender Versions And Known Issues
Different Blender versions have had different issues with this tool. Here’s a comparison of major versions and the status of Pick Shortest Path:
| Blender Version | Status | Notes |
|---|---|---|
| 2.79 | Limited | Few options, some bugs |
| 2.80–2.83 | Improved | More stable, still minor bugs |
| 2.90+ | Stable | Most problems fixed |
| 3.0+ | Best | Extra features, reliable |

Advanced Insight: What Beginners Often Miss
- Element Type Matters: The tool only works if both selected elements are the same type—two vertices, two edges, or two faces. Mixing types will not work.
- Hidden Geometry: Sometimes, geometry is hidden (using H key). The shortest path cannot cross hidden parts, so unhide everything before using the tool.
- Selection History: Blender sometimes uses the order you select elements. Select the start, then Shift-select the end.
When To Use Alternatives
If Pick Shortest Path still doesn’t work, consider these alternatives:
- Select Edge Loop (Alt+Click): Fast for clean loops.
- Select Linked (Ctrl+L): Selects all connected elements.
- Manual Selection: For very complex or broken meshes, manual selection may be faster.
- Add-ons: Some Blender add-ons provide enhanced selection tools for advanced needs.
Frequently Asked Questions
What Does “pick Shortest Path” Actually Do In Blender?
It selects the shortest connection of vertices, edges, or faces between two selected elements on a mesh. This helps in editing, UV unwrapping, and complex modeling tasks.

Why Is The Tool Not Working Even After Updating Blender?
If updating did not solve the problem, check for non-manifold geometry, disconnected mesh parts, or hidden geometry. These issues often block the shortest path even in newer versions.
Can I Use Pick Shortest Path In Sculpt Or Object Mode?
No, this tool only works in Edit Mode for mesh objects. It does not work in Sculpt, Object, or other modes.
Is There A Limit To The Distance Between Selected Elements?
Blender can only find a path if there is an unbroken chain of connected elements. If the elements are too far or not connected, the tool will not work.
Where Can I Find More Details And Official Documentation?
You can read more about this tool at the Blender Manual.
If you take time to understand why Pick Shortest Path sometimes fails, you’ll work faster and with less frustration. Practice on simple meshes, watch for non-obvious issues, and update Blender to the latest stable version for the best experience.
