UV Editor marking menus

Shift + Right-click

Shift + right-clicking in the UV Editor opens a marking menu that shows different items depending on the type of components that are selected.

Common Menus

These menu options are shared no matter which component mode is currently active:

Menu Item	Effect
Unfold	Repositions the selected UVs so that they lay flat in the UV space.
Optimize	Evens out the spacing between selected UVs, which can help fix distortions.
Tools	Provides quick access to the UV Toolkit's Transform > Tools section.
Pinning	Provides quick access to the UV Toolkit's Pinning section.
Selection Constraints	Limits the components you can select to those matching a chosen criteria.
Transform Constraints	Limits UV movement to sliding along their adjacent edges.
Toggle Shell Borders	Determines whether or not to display shell borders in bold.
Texture Borders	Display texture borders in bold.
Display Image	Displays the texture image in the UV Editor.
Checker Map	Displays a checker map pattern used for viewing distortions.
Distortion Shader	Displays a color map used for viewing distortions.

UVs

When UV texture coordinates are selected, the marking menu shows the following operations:

Menu Item	Effect
Snap	Gives you access to various snapping options in the UV Toolkit's Align and Snap section.
Normalize	Scales the selected UVs to fit within the 0-1 UV space.
Straighten	Repositions all selected UVs so they form a straight line in the chosen directions.
Layout	Repositions UV shells so they don't overlap and make maximum use of the available UV space.
Align UVs	Gives you access to various alignment options in the UV Toolkit's Align and Snap section.
Rotate UVs	Pivots selected UVs around the current pivot point denoted by the UV Toolkit's Transform section.
Distribute	Evenly spaces the selected UVs.
Flip	Flips the positions of the selected UVs in the specified direction.
Map Border	Maps the currently selected UV to 0, 0 in UV space, then spreads out all other border UVs relative to that.
Symmetrize	Mirrors the current selection across a chosen axis of symmetry.
Unitize	Repositions the selected UVs onto the border of the 0-1 UV space.
Auto Seams	Automatically identify and select the best edges for seams.
Create UV Shell	Creates a new UV Shell from the selected components.
Cut UVs	Creates seams along the edges attached to the selected UVs.
Delete UVs	Removes the selected UVs.
Merge UVs	Merges the selected UVs into a single UV.
Sew UVs	Merges the edges attached to the selected UVs.
Measure Pixel Distance	Displays the distance between two chosen UVs in pixels.

UV Shells

When UV shells are selected, the marking menu shows the following operations:

Menu Item	Effect
Mapping	Gives you access to various mapping options in the UV Toolkit's Create section.
Flip Along U / Flip Along V	Mirrors the entire shell horizontally / vertically.
Layout	Repositions UV shells so they don't overlap and make maximum use of the available UV space.
Align UVs	Gives you access to various alignment options in the UV Toolkit's Align and Snap section.
Rotate UVs	Pivots selected UVs around the current pivot point denoted by the UV Toolkit's Transform section.
Auto Seams	Automatically identify and select the best edges for seams.
Match Grid	Attempts to line up the UVs adjacent to the selected faces to the grid.
Match UVs	Moves UVs adjacent to the selected faces, within a certain tolerance distance, to the average of their individual positions.
Normalize	Scales the selected UVs to fit within the 0-1 UV space.
Straighten Border	Repositions all border UVs on the selected shell so they form horizontal/vertical straight lines.
Straighten UVs	Repositions all UVs on the selected shell so they form horizontal/vertical straight lines.
Unitize	Repositions the selected UVs onto the border of the 0-1 UV space.
Distribute Shells	Evenly spaces the selected shells according to the method chosen.
Gather Shells	Moves all UV shells to the 0-1 UV space.
Orient Shells	Rotates all UV shells so they face the same direction.
Randomize Shells	Randomly arranges UV shells within the 0-1 UV space.
Snap and Stack Shells	Moves multiple UV shells on top of one another by overlapping the selected UVs on each.
Stack and Orient Shells	Stacks selected UV shells on top of each other and rotates them so they face the same direction.
Stack Similar Shells	Stacks only shells that are topologically similar on top of each other.
Unstack Shells	Moves all selected UV shells so they no longer overlap while keeping them close together.

Edges

When a polygon edge is selected, the marking menu shows the following operations:

Menu Item	Effect
Move and Sew UVs	Merges the selected UV edges while simultaneously moving the affected shells so they do not become distorted.
Orient Shell to Edges	Rotates the UV shell to line up with the most selected edges.
Straighten Shell	Attempts to untangle all UVs along/within the border of a UV Shell.
Unfold	Repositions the selected UVs so that they lay flat in the UV space.
Optimize	Evens out the spacing between selected UVs, which can help fix distortions.
Cut	Splits the selected UV edge into separate overlapping UV edges.
Sew	Merges the selected UV edges.
Stitch Together	Sews two selected edges together by moving one shell towards the other in the specified direction..

Faces

When a polygon face or UV shell is selected, the marking menu shows the following operations:

Menu Item	Effect
Mapping	Gives you access to various mapping options in the UV Toolkit's Create section.
Normalize	Scales the selected UVs to fit within the 0-1 UV space.
Straighten UVs	Repositions all UVs adjacent to the selected faces so they form a straight line in the chosen directions.
Create UV Shell	Creates a new UV Shell from the selected components.
Rotate Faces	Pivots selected faces around the current pivot point denoted by the UV Toolkit's Transform section.
Cycle	Rotates the U and V values of the selected components.
Flip	Flips the positions of the selected UVs in the specified direction.
Match Grid	Attempts to line up the UVs adjacent to the selected faces to the grid.
Match UVs	Moves UVs adjacent to the selected faces, within a certain tolerance distance, to the average of their individual positions.
Symmetrize	Mirrors the current selection across a chosen axis of symmetry.
