Jordi Vall-llovera Medina demonstrates an Addon he has created for Transforming UV Islands in Blender called Island Tools. Island Tools can be useful for transforming UV shells or “islands” around to better fir the UV coordinate space by allowing you to tweak, scale or transform the UV shells easily. Check out the Island Tools here, and [direct download] Island Tools for Blender here.
The Island Tool Addon features:
- Only selection : Only applies operations on previously selected uv islands
- View all selected : Display output as selected / unselected uv islands
- Link size : Link scale sizes for uniform transforms, then only takes into account X size for transformation
- X size : Scale uv islands from every own local X axis
- Y size : Scale uv islands from every own local Y axis
- Rotation : Rotate uv islands from own local center
- X mirror : Mirror uv islands from every own center on X axis
- Y mirror : Mirror uv islands from every own center on Y axis
