Cut graphs into sub-graphs using Unity's own graph cut function

Reproduced, the cattle are everywhere, I am too small

Although there are many tools on the Internet to cut the graph function, but most of them are automatically cut or according to the plist files,

This kind of cutting is often not self-tuning or difficult to adjust, resulting in unsatisfactory results.

Today Stroll Bar found a netizen wrote the cut diagram plugin is very good, share the next,

The use of unity with the graph cutting function, the original cutting function although very convenient and easy to fine-tune, but can not be exported, the netizen exported them,

This code will not take effect until the asset/editor directory is added.

Based on the above steps,

In the picture set that you want to want $ right-click Sprite Sheet Packer, Process to Sprite

After that, a folder with the same Atlas file name will be generated in the same directory, with each resource of the want $ atlas.
