Learning 2D Game Development with Unity®: A Hands-On Guide to Game Creation

Packing Tag

We briefly covered the Packing Tag in the Texture Import Settings of the p1_spritesheet. The Packing Tag lets you define a name so that you can pack all the sprites that share the same name. You could create a Packing Tag for a bunch of sprites called “tiles” and then use that tag for creating your sprite sheet.
