Simple Blender UV Editor Tool to align selected UVs to the selection minimum or maximum. It's best explained with a video:
Installation:
- Download the repository as a zip file
- In the Blender User Preferences menu, go to the Add-ons tab, and click Install Add-on from File
- Install the zip file
- The Add-on can now be found under UV as BRM_UVAlignMinMax
It will add the tool by default to the Tools tab in the UV editor. You can turn this off in the Add-on preferences if you prefer using shortcuts. Shortcuts can be set up from the buttons.
Enjoy!
