Viewport Overlays

Using the Viewport Overlays pop-over settings for the overlays can be configured.There is a switch to turn off all overlays for the 3D View.

The options that are visible in the pop-over depends on the mode that the 3D View is in.

Object Mode

The next options are always present, independent the current mode.

Guides

  • Grid
  • Show grid in orthographic side view.
  • Floor

  • Show the ground plane.

    • X/Y/Z
    • Show the X and/or Y and/or Z axis line.
  • Scale
  • The distance between lines in the grid/floor.
  • Subdivision
  • The number of subdivisions between grid lines.
  • Text Info
  • Show text overlay.
  • 3D Cursor
  • Show the 3D Cursor overlay.
  • Annotations
  • Show the annotation overlay.

Objects

  • Extra
  • Show details of objects including empty wires, cameras and other visual guides.
  • Relationship Lines
  • Show dashed lines indicating parents or constraint relationships.
  • Outline Selected
  • Show an outline highlight around selected objects.
  • Bones
  • Show Bones. Disable to only show their motion path.
  • Motion Paths
  • Show the motion path overlay.
  • Origin
  • Show the object origin of the active object.
  • Origin (All)
  • Show the object origin of all objects.

Geometry

  • Wireframe

  • Show the face edges overlay.

    • Wireframe
    • Adjust the number of wires to display. 1.0 means show all wires.
  • Face Orientation
  • Show the face orientation overlay. In the face orientation overlayall faces where the face normal point towards the camera are colored blue.All faces where the face normal point away from the camera are colored red.With this overlay it is easy to detect the orientation of the face normals.

Motion Tracking

Show the motion tracking overlay.

  • Camera Path
  • Show the reconstruction camera path.
  • Marker Names
  • Show the names for reconstructed track objects.
  • Tracks

  • Change the display of the reconstructed tracks.

    • Plain Axes
    • Arrows
    • Single Arrow
    • Circle
    • Cube
    • Sphere
    • Cone
  • Size
  • Change the display size of the recontructed tracks.

Mesh Edit Mode

The next options are available when in Edit Mesh Mode.

  • Edges
  • Highlighted selected and partially selected edges.

Only affects vertex and face selection mode (as edges are always highlighted in edge-selection mode).

  • Faces
  • Highlight faces using a face overlay that applies to both selected and unselected faces.

Affects all selection modes.

  • Center
  • Show face-center points in solid shading modes.

Only affects face-select mode.

  • Creases
  • Display edges marked with a creasefor the Subdivision Surface Modifier.
  • Sharp
  • Display sharp edges, used with the edge split modifier.
  • Bevel
  • Display weights created for the Bevel Modifier.
  • Seams
  • Display the UV unwrapping seams.
  • Edge Marks and Face Marks
  • Used by Freestyle.

Shading

  • Hidden Wire
  • Show only front-facing wireframes.This is useful for a re-topology workflow.

Tip

Optimally this could be combined with the X-Ray display setting.

  • Vertex Groups Weights

  • Display weights in Edit Mode.

    • Zero Weights
    • Display unweighted vertices:

None:Active:Show vertices with no weights in the active group.All:Show vertices with no weights in any group.

Mesh Analysis

Show the mesh analysis overlay.

See: 网格分析.

Measurement

Numerical measures of the selected elements on screen as part of the text info overlay.The 单位 can be set in the Scene properties.

  • Edge Length
  • Shows the length of selected edges.
  • Edge Angle
  • Shows the angle of selected edges between two faces.
  • Face Area
  • Show the area of selected faces.
  • Face Angle
  • Show the angle of selected face corners.

Tip

Geometry connected to the selection is shown while transforming,allowing you to move a vertex and see the connected edge lengths for example.

Note

These values respect Global/Local.

Use Global if you want the Object's scale to be applied to the measurements.

Normals

  • Display vertex normals
  • Display face normals at vertices (split normals)
  • Display face normals
  • Size
  • The size to show the selected normals.

Developer

  • Indices
  • Display the indices of selected vertices, edges and faces.

Freestyle

  • Edge Marks
  • Display Freestyle edge marks, used with the Freestyle renderer.
  • Face Marks
  • Display Freestyle face marks, used with the Freestyle renderer.

Sculpt Mode

  • Show Diffuse Color
  • Show diffuse color of object and overlay sculpt mask on top of it.
  • Mask
  • Show mask as overlay on object. The opacity of the overlay can be controlled.

Vertex Paint

  • Opacity
  • The opacity of the overlay.
  • Show Wire
  • Use wireframe display in paint modes.

Weight Paint

  • Opacity
  • The opacity of the overlay.
  • Zero Weights
    • Zero Weights
