Unity Texture Atlas Creator

• The Texture Atlas Creator was designed to help you doing simple tasks directly from the Unity Editor it simplify the process (and saves time) of creating texture Atlases or collections with extra tools.

• The Editor was just intended to collect and stack 2DTextures into a Atlas with ease, Then it became something else and I do plan on updating it but for now it is what it is!.

• I might make a more complex version with more structure, but I want this to be all in one file.
  

• Expect some bugs when it's coming to edge cases and I'm open to adding more features upon request.

• For a quick look at the editor see: Screenshots.
