Cut UV Tool

The Cut UV Tool lets you split UVs by dragging along edges. Press Ctrl to temporarily activate the Sew UV Tool and weld UVs together.

To open the Cut UV Tool, select it from the Cut & Sew section of the UV Toolkit or select Tools > Cut from the UV Editor menus.

The following options appear in the Tool Settings window when you select Tools > Cut > .

Brush Options

Edge Select Sensitive
Specifies the radius of the tool. Higher Edge Select Sensitive values increase the radius. Any edges that are within the radius when you drag your cursor across a shell are cut.
Steady Stroke
Helps to produce a smoother stroke by filtering mouse movement. When on, a vector displays on the tool cursor and no cut appears until you drag a distance equal to the length of the vector. The length of the vector is set by the Distance setting.
Distance
Sets the length of the Steady Stroke vector on the tool cursor.
Cut Open Ratio
Specifies the size of the gap between the split UVs. A higher value produces a wider gap.
Display All Shell Borders
When on, highlights shell borders. Sets of connected edges are displayed in different colors, making it easy to identify edges that are shared. Display All Shell Borders is off by default.
