Pressing Alt + H will unhide any hidden objects in Blender's Edit Mode.
Understanding Hidden Geometry in Blender's Edit Mode
Sometimes, parts of your mesh in Blender's Edit Mode might disappear, leading you to believe Edit Mode isn't working correctly. This often happens when you accidentally hide specific vertices, edges, or faces. Blender offers tools to hide and unhide these elements for better control during modeling.
Methods to Unhide in Edit Mode
Here's a breakdown of how to unhide geometry in Blender's Edit Mode:
- Alt + H (Unhide): This is the primary shortcut to reveal all hidden vertices, edges, and faces in the currently selected object. This will undo any hiding actions you've taken in Edit Mode.
- Mesh Menu > Show/Hide > Reveal Hidden: You can also access this command through the Mesh menu at the top of the 3D viewport in Edit Mode. Navigate to Mesh > Show/Hide > Reveal Hidden to unhide everything.
Why Parts of Your Mesh Might Be Hidden
Understanding why parts of your mesh are hidden can prevent this issue from recurring:
- Accidental Hiding: You might unintentionally press the 'H' key while having certain vertices, edges, or faces selected. This hides the selected elements.
- Isolation: Blender allows you to isolate selected portions of a mesh for focused editing. Using 'Shift + H' isolates the selection, hiding everything else.
- Face Sets or Vertex Groups: These tools can be used to manage parts of a mesh and hide them temporarily.
Troubleshooting
If using Alt + H doesn't work, consider these potential issues:
- Object Mode vs. Edit Mode: Ensure you're actually in Edit Mode. The object must be selected, and the mode dropdown in the top-left corner of the Blender window should display "Edit Mode".
- Wrong Object Selected: Double-check that you've selected the object that has the hidden geometry.
- Layers/Collections: Verify that the object itself isn't hidden in the Outliner (the panel on the right side of the Blender window). Look for the eye icon next to the object's name. If it's greyed out or missing, the object is hidden. Click the icon to unhide it.
- Viewport Filters: In the top right of the 3D Viewport are several icons (overlays, gizmos, shading). Make sure the "Show Overlays" is toggled on, otherwise you might not be able to see the geometry you have revealed.
