The radius of the brush controls the offset. Sew - Connects UV vertices along border edges using brush strokes.Right-clicking and dragging controls the brush radius.

Split - Separates UVs from each other along the edges connected to the selected UV points, creating borders using brush strokes.

The following mode options are available: Splits and sews UVs interactively with a brush by moving one shell towards another in the specified direction. The following Split and Sew options are available:Дepending on the command key and option selected, the interface updates, allowing you to quickly adjust your UVs. Note:If a brush stroke only covers a single vertex, or a set of unconnected vertices, those are split along all connected directions.Д¬lick on the thumbnail to view an animation. Note:UV points within the brush radius are sewn together with other points for the same vertex, as long as they are also within the brush radius.Д¬lick on the thumbnail to view the animation. Tip:Alternatively, to automatically switch from Split to Sew mode, hold the Shift key and click and drag on the vertices to sew the edges together. Newly created UV points are positioned along the connected edge that is perpendicular to the cut.ДЇrom the UV Split & Sew options, set the Mode to Sew.Д¬lick and hold the mouse on a UV edge and drag it along the split seam. The UV island splits apart, with the offset controlled by the brush radius. With the Edges selection mode enabled, click and drag your mouse over a UV edge. Right-click and drag the mouse to change the radius of the brush.ДЇor more information, see Customizing Paint Tools. To split and sew edges of an UV island: 1.ДЇrom the UVВ Split and Sew options, set the Mode to Split. The UV Split & Sew options are displayed in the lower portion of the Toolbox. The purple edges indicate that they are the geometric equivalent of the selected orange edges. Tip:Alternatively, you can set the selection mode to Polygons or Vertices to make a selection. Alternatively, setting the Mode to Sew and clicking on vertices sews the edges together. Holding the Shift key while right-clicking and dragging your mouse on the vertices, sews the edges together. Applying the tool over vertices in the UV space, with the Mode set to Split, separates them apart, with the brush radius controlling how far they are offset from their starting position. This tool acts like a brush, with the radius controlling the results. The Split and Sew Tool allows you to change the layout of UVs by dragging your mouse over them.

In the Toolbox, select Split and Sew Tool.ДЇor more information, see Split and Sew Tool Options. Select a number of edges on one island in the UV Editor. Tip:Alternatively, you can use the Vertices or Polygons selection modes. With your mesh already loaded, open the UV layout. Join small shells to reduce the number of seams to minimize distortion.ДЇor more background information, see Working with UV Maps.Correct UV texture coordinates, which may be distorted or are overlapping shells in the UV Editor.Separate one shell into multiple shells to correspond to different parts of a texture.Use the Split and Sew tools to complete a number of operations: (A UV island is a connected group of polygons in a UV map.) The move operation translates the entire UV island to facilitate the merger of separate UV shells. The sew operation converts discontinuous UV data into continuous data to stitch UVs together. The Split and Sew tools allow you to merge UVs together.
