Cut UV Active Tool

Cut UV Active Tool#

The Cut UV tool is the primary tool in the UV Flow add-on and is located in the Edit Mode toolbar. When activated, it provides a pre-selection highlight for edges and faces as you hover over your mesh.

Marking Seams#

You can use the Cut UV Tool to interact with edges using the following actions:

  • Left Mouse Button (LMB): Mark edge as seam

  • Alt + LMB: Clear edge as seam

  • Double LMB: Mark loop as seam, stopping at other seams

  • Shift + Double LMB: Mark entire loop as seam

  • Alt + Double LMB: Clear loop as seam, stopping at other seams

  • Alt + Shift + Double LMB: Clear entire loop as seam

  • Drag LMB: Draw a marked seam path

  • Alt + Drag LMB: Draw a clear seam path

The following hotkeys are also available for those using Emulate 3 Button Mouse or other alternative keymaps:

  • Alt + RMB: Clear edge as seam

  • Alt + Double RMB: Clear loop as seam, stopping at other seams

Tip: While drawing to mark or clear seams, use the dots of neighboring vertices as targets. You can also erase by dragging backward toward the red dot.

Selecting#

While using the Cut UV tool, you can also select faces:

  • LMB: Select a face.

  • Double LMB: Select the UV island the face is connected to.

Double-clicking to select a UV island is particularly useful for hiding or pinning sections of a mesh that you have already unwrapped. It also frames the selected island in the UV Editor if that is enabled in the add-on’s preferences.

Tip: You can still select or deselect edges in UV Flow with Shift LMB and Ctrl Shift LMB, which is useful when straightening.

Tool Settings#

One of the main benefits of using the Cut UV tool is the easy access it provides to all of the commands you need for the whole unwrapping process.

Options for unwrapping, straightening, and packing are all conveniently placed in its tool settings, as well as options for managing the object’s UV layers and display. These can be found in the tool settings section of the 3D View header if you have it enabled, in the sidebar under Tool, or in the Tool section of the Properties Editor.
