The Demo version is free, but expires after 30 days; you will need to purchase a license if you want to keep on using UVLayout after that. Note: After 6 months the lock resets, so you will be able to test future releases if you decide to not purchase the current version.

Download the UVLayout DMG file, then open it up and follow the instructions in the Read-Me.txt file. Plus if you don’t already have XQuartz installed, download and install that as well. See Installation_Guide:_OS_X for full installation instructions.

After installation, you can run UVLayout by drag’n’dropping OBJ files onto the “UVLayout Demo” application icon.
