Unity Shoebox Extract Sprites to unity format

Cut for a transparent picture

You can use the shoebox Extract Spritesfunction, drag the picture onto the Extract Sprites feature icon and the image will be automatically cut as shown in:
Click SettingsYou can set the Clusters merge sub items to False, do not merge subkeys, change the File Name to Slice##.png, and click ApplyCan. and then press SaveYou can export the cut picture. As shown in the following:
The build includes a text document that records the coordinates of the sub-graphs for each cut. In the Editor directory of Unity, add the following script: C # Code

In Project view, select this text document, right-click on the function shoebox→process to Sprites, and automatically complete the import into Unity Sprites format, as shown in:
Unity's Sprite Editor also comes with the ability to cut pictures, but when it comes to complex Atlas, the cut is confusing, with a shoebox accuracy ratio.
