🔧 Features

Unwrap

• Unwrap: Unwrap while maintaining the original position, size, and angle as much as possible
• Straight: Unwrap so that the selected edge loop becomes a straight line
• Normalize: Normalize the size and position of selected UVs
• Gridify: Unwrap so that the selected face becomes a rectangle. Can be used for quadrilateral meshes
• Rectify: Unwrap so that the boundary becomes a rectangle
• Projection Unwrap: Unwrap by projecting from an angle parallel to the normal of the face selected in the 3D view

Align

• Align: Align selected elements to the top, bottom, left, right, or XY center position
• Align Vertical/Horizontal Edges Only: Align edge loops only in vertical or horizontal directions
• Align Axis: Adjust to be vertical to the X or Y axis.
• Orient World: Align the angle of the island to the Z axis
• Sort: Sort islands based on coordinates in 3D space
• Distribute: Distribute islands evenly / Distribute UVs based on geometry/equalize edge length(v1.3)

Vertices
