UV Editor - Header

The Header contains various menus, navigation elements, settings and tools for the viewport. This content differs, dependent of the sub mode.

The header is divided into two areas. Left mode and menus. Right settings.

Switch to UV / Image editor

Sometimes you want to switch from the UV Editor to the Image Editor. Or vice versa. To continue at the unwrap or to paint a texture.

This two editors are connected by a menu that allows exactly that. A button in each header that switches to the other editor.

Header right click menus

The general right click menu functionality is explained in chapter 6 Editors introduction.

Editortype Menu

Bforartists is made of several editor types. Headers can display a menu where you can switch to other editor types.

This menu is hidden by default. It is meant to edit the layouts, and should not be necessary for regular work. You can reveal it in the header right click menu.

Sub Modes

The UV Editor has two sub modes. Sync Off and Sync On.

UV Select Sync off

With UV Select Sync off you will be able to modify single UV elements, like whole UV patches. And the 3D view will not change its selection.

When you have some geometry in the 3D view not selected, then it will not show up in the UV image editor neither.

You can switch between the selection modes with hotkeys 1, 2, 3, 4

Vertex selection mode

Select vertices in the UV geometry.

Sticky Selection mode

Disabled

No sticky selection. You can just move one UV vertice at time. In case you have two vertices above each other, like with a UV patch with two faces, then just one vertice gets selected. Even when it's the same UV patch.

Shared Location

Selects all UV vertices under the mouse in case it's part of the same UV patch. Vertices of other UV patches gets ignored.

In this shot the two down left faces are one UV patch.

Shared Vertex

Selects all UV vertices that shares the same vertice at the 3D mesh. Regardless if it's the same UV patch or not.

UV Select Sync on

With UV Select Sync on you will keep selections of UV space and 3D view in sync. But you cannot modify single UV elements anymore. In this mode you work with Vertices, Edges and Faces.

All UV geometry of the object will show up, no matter what's selected in the 3D view.

You can switch between the selection modes with hotkeys 1, 2, 3. Note that this selection mode is in sync with the selection modes in the 3D view. When you change it in the one editor, then it changes in the other editor too.

Vertex selection mode

Select vertices in the UV geometry and at the 3D mesh object.

Header Tools and Options

UV Editor - Header Tools

The header contains several tools, dependent of what you do and what tool set is selected.

Pivot

What pivot point to use for selected elements.

When you rotate or scale an UV patch, or a group of vertices/edges/faces, you may want to set the pivot point to a specific location of the selection. The names should be self explaining.

Snapping

Activate snapping when transforming an element.

Snapping can be temporarily activated by holding Ctrl key. So no need to turn snapping on and off all the time.

Proportional Editing

Enables proportional editing.

Proportional Editing is a way of transforming selected elements (such as vertices) while having that transformation affect other nearby elements with a falloff. For example, moving a single vertex will move unselected vertices within a given range. And the falloff means that selected vertices that are closer to the selected vertex will move more than those farther from it.

Settings

The settings appears when you activate Proportional Editing. Choose between different falloff methods for the proportional editing. The settings hides when proportional editing is off.

Proportional Size

When proportional editing is on then you will see a black circle around the selection that defines the influence area of the proportional editing.

This value can be adjusted with the scroll wheel, the page up and page down hotkeys, and in the last operator panel of the transform tools.

UV Map Property

A mesh can have more than one UV map. You create them in the Properties editor in the Object Data Properties tab in the UV Map Panel.

The property in the header allows you to switch to another UV map, and to rename the UV map.

Image Prop

This property contains the list of loaded images. When no image is loaded then it displays the New and Open Buttons. When an image exists then it displays the name of the currently selected image.

From left to right ...

Remove

Removes the image.

New Image

Create a new image.

Creates a new image. You will get a dialog where you can define settings for the new image.

Color

Adjust the color of the new image. A click will call a color picker.

Check this checkbox if the new image should have an alpha channel.

Generated Type

Here you can define what kind of texture you want to create.

Blank is one plain color.

UV Grid is a checker texture in black and white.

Color Grid is a colored checker texture.

32 Bit Float

Check this checkbox if the image should be in 32 Bit floating point bit depth per channel. Else it is in 8 bit per channel.

Duplicate

Not supported here.

Unlink Datablock

This deletes the selected image. Unfortunately not immediately. You need to save the scene and to reload it.

And you need to make sure that it is not linked to anything else. A mesh or a fake user for example. Have a look if there is a number besides the F button. When this is the case then the image has still a user, and so still loads with loading the scene.

Use Image Pin

When you select another object. for UV mapping for example, then usually the connected images for this object gets displayed. Use image pin nails the currently selected image so that it stays displayed.

• Corner: UV vertices snap to the nearest pixel corner.
• Center: UV vertices snap to the center of each pixel.

Quick Menu

Quick Menu

The quick menu, or in long Quick Favorites menu, is a menu that can be customized to your needs. Here you can add operators for quick access.

It is located in the header. But it can be called by hotkey Q directly under the mouse. This hotkey works in other editors too.

When the menu is empty, then you will see the message "No Menu Items found". This means that you first have to add some tools to the menu. It is a user configurable menu.

Note that added operators in this menu does not have icons. Just text.

Note also that the Quick menu for the UV editor shares the content with the Quick menu from the Image editor.

Adding an operator to the Quick menu

Open the panel or the menu where your operator is that you want to add.

Let's add the open command from the File menu. Open the File menu, right click at open, and choose Add to Quick Favorites.

Do the same with Save As. We should now have two new menu items in the Quick menu, which you can use now.

As a rule of thumb, when the right click menu has an Add to Quick Favorites, then you can add it to the quick menu.

Note that you can also add operators from the tool shelf at the left. And also operators from other editor types. Some other editors have their own quick menu though. The Image Editor for example. These operators gets added in the quick menu of the image editor then. And does not show in the quick menu in the header of the 3D view.

Adding a menu to the Quick menu

It is also possible to add a menu to the Quick menu. For example the whole Add menu. The way is the same. Right click at it, and choose Add to Quick Favorites.

Order

You might notice that the add menu adds at the top of the menu, and not at the bottom as you would expect. First comes menus, then comes operators. And they get added in the order in which you add them.

Besides that, operators and menus gets added in the order that you add them. They cannot be sorted afterwards. So be careful how you add them. You can of course always remove operators and menus, and re-add them at the end of the list.

Removing an operator from the Quick menu

The Quick Favorites menu (Q) holds the tools and menus you add to it yourself. See Quick Favorites in the Interface chapter.

Context and mode dependent content

The quick favorites. menu exists in nearly all editors. But it is just in the 3D view available in the header. So that you know this functionality exists. In the other editors you call it with hotkey Q.

The content of the quick favorites. menu changes, dependent over which editor you are, and in what mode you are. When you add for example an operator from the image editor, then this operator just shows in the quick menu when you call the menu from the image editor. Same goes for the modes. Edit mode tools will just show in edit mode. And so on.

Pin

Pins the selected vertices . This vertices are now nailed for the unwrap algorithms Angle based and Conformal. Their positions will not change when you repeat the unwrapping. And the algorithms will try to fit the rest of the geometry to this pinned vertices.

Pinned vertices are marked red.

A use case is for example when you have a distorted result for symmetric geometry like a face with the Conformal method. Then you can try to align two center vertices, pin them, and repeat the conformal method. It may be more symmetrical afterwards.

Adjust Last Operation - Merge UV's by Distance

Split Selection

Splits the selected geometry. UV Sync Selection needs to be off.

Pack Islands

Pack Islands tries to pack the selected UV geometry as close together as possible. Without to waste too much empty space.

Note that the algorithm fails at round geometry. It calculates with rectangle shapes.

Pack Islands Popup

When you click the operator then you will see a popup panel where you can adjust the further settings.

Shape Method

How the islands are packed.

Scale

Scale islands to fill the unit square.

Rotate

Rotate islands to improve layout.

Rotation Method

Scaled

Use scale of existing UV's to multiply margin.

Add

Just add the margin. And don't use the UV scale for calculation too.

Fraction

Specify a precise fraction of final UV output.

Lock Pinned Islands

Merge Overlapping

Overlapping islands stick together.

Pack To

Average Island Scale

Scales the selected UV geometry to have the same relative size than the rest of the mesh. So that the texels at the mesh have roughly the same size everywhere.

Minimize Stretch

You might end in a UV mapping result that still shows unwanted distortions here and there. For example when you UV map a human face. Minimize Stretch tries to minimize this stretching effects in the UV patches.

To view stretched areas at your UV patches, tick Display Stretch in the Overlays panel, and switch from Angle to Area. Then a stretch mask gets displayed. The color range goes from blue to green to red, where blue is minimal stretch and red is maximal stretch.

Let's explain it with an example. A sphere where the cut is nearly at the pole. And UV mapped with Angle Based. The result will of course show heavy stretched areas.

Note that the UV geometry must be selected in the UV Image editor. Now let's use the Minimize stretch tool. The algorithm now first tries its best to find the best fitting result that shows fewest stretching across the overall UV geometry.

The header shows a help text while the algorithm works. The Blend factor is the value between the original unwrapped UV mesh, and the maximum minimized stretch. You can set this value manually by using the scroll wheel at your mouse, or with the + and - keys.

Adjust Last Operation - Minimize Stretch

Stitch

Stitch tries to union UV patches along the selected edges or vertices.

Adjust Last Operation - Stitch

This last operator appears in the 3D view.

Operation Mode

The operation mode. Calculate with Edges or Vertices.

Mark Seam

The unwrap algorithms Angle based and Conformal requires to have edges marked as seams. Think of it as a cutting pattern for a trouser for example. Such a trouser is also made of fabric patterns.

Same goes for the UV patches when you use Angle based or conformal unwrapping. You need to cut your mesh into parts and mark edges as seams, so that the algorithm knows where the seams are.

Mark seam marks the currently selected edge(s) as a seam. Seam edges will be displayed as red in the 3D viewport. But not in the UV Image Editor. The UV patches represents the seams.

You need to unwrap the mesh again when you want to apply changes by the new marked seams.

Adjust Last Operation - Mark Seam

Clear

Clears the seam instead of marking it.

Clear Seam

Clear seam removes the seam from the currently selected edge(s) in the 3D view.

Seams from Islands

Unwrapping creates the UV geometry from the 3D object. You mark the seams, then you click at unwrap, and the UV mesh gets created.

Mark Seams from islands goes the other way around for marking seams. It creates the seams at the mesh object in the 3D view from the UV geometry in the UV Image Editor.

A use case is when you import meshes. Then you usually just have the UV patches in the UV Image editor. And when you want to modify the UV's further, then you need the seams at the mesh.

Align/Arrange Islands

Provides a unified interface for aligning, distributing, and organizing UV islands based on axis, order, and spacing. Ideal for texture atlases, modular layouts, and precision packing.

Aligns selected UV islands along a chosen axis.

Adjust Last Operation - Arrange/Align Islands

Initial Position

Defines how the alignment reference is calculated for each island. This determines where each island "snaps" during alignment—e.g., top edge, center, or bottom edge.

Axis

Specifies the direction along which islands will be aligned. X or Y. Useful for stacking islands top-to-bottom or side-by-side.

Align

Controls which part of the island is aligned to the axis. This affects how islands are visually positioned relative to each other.

Order

Determines the sequence in which islands are arranged.

Margin

Sets the spacing between islands after alignment. Adds consistent padding between islands to avoid texture bleeding or overlap.

Value

Float input (e.g., 0.050)

Set User Region

Defines a custom region within the UV Editor viewport, allowing you to isolate, focus, or constrain operations to a specific area of the UV space.

Use

An example is for Packing Islands: Limit packing to a specific region (e.g. top-right quadrant of the UV space). This can be used to constrain packing or alignment operations.

This can also serve as a reference zone for manual editing or snapping.

To toggle visibility after defining it manually, use the Options drop down to the top right of the header.
