Lets you select and reposition a UV shell in the 2D view of the UV Editor by selecting a single UV on the shell. You can automatically prevent the repositioned UV shell from overlapping other UV shells.
To open the Move UV Shell Tool, select from the UV Editor menus.
The following options appear in the
Tool Settings window when you select
Tools > Move UV Shell > 
.
Move UV Shell Settings
- Prevent overlap
-
The Prevent overlap setting restricts a UV shell from being accidentally moved to a position where it would overlap existing UV shells in the UV Editor view. It is on by default. For example, if you select and move a UV shell and reposition it to an area that is already occupied by an existing UV shell, the selected shell will do one of the following:
- Snap back to its previous location (when the overlap is large).
- Snap to the closest location possible based on the direction you dragged the UV shell (when the overlap is small).
- Shell spacing
-
Specifies the distance the repositioned UV shell will be separated from other existing UV shells as a percentage of the map size when Prevent overlap is turned on.
- Placement iterations
-
Specifies the number of times the tool checks between the start and end positions when translating one or more UV shells in order to optimally achieve the Shell spacing distance without snapping back to the original location. A higher number produces the closest result possible, but takes longer to complete the move. The number of selected UV shells also affects the time to complete the move. The default setting is 16.
