Requires Unity 3.5.7 or higher.
Some times you have a nice tiled 2D map but no tileset. Map2Tileset can help you slice tiled 2D maps into tilesets and create a .tmx tileset file to be used with any tile editor such as 2dtoolkit or Tiled.
Notice:
1. Map2Tileset will modify the selected texture’s Texture Type to “Advanced”, Non Powerof2 to “None”, and Read/Write attribute to “TRUE”.
Update: Version 0.99 1/24/2015
Added two options for more complex situations
1.offset from top-left: it can support the actual map area are not aligned on the edges of the material conditions .
2.map size: It can support you need only deal with part of the map.
