Spritato is a tool that allow graphic designers to export layers from a layered image file in PSD format to PNG files. Those exported files are generally used as source files for further processing such as importing into a game engine or an animation software to create games or animations.
Important:
Not all features of PSD are supported. To work around those unsupported features, the general approach is to encapsulate them in Smart Object or merge / apply them to normal pixel layer before saving the PSD file. Feel free to start the free trial to see if Spritato is right for you.
