Select the 2D image you want to edit from the Project View (Fig 1: Project View).

(See Fig 2: Texture Import Inspector… below.) Opening the Sprite Editor Sprite textures with multiple elements need the Sprite Mode to be set to Multiple in the Inpsector.

For information on importing and setting up sprites, see Sprites. Make sure the graphic you want to edit has its Texture Type set to Sprite (2D and UI). Unity makes it easy to extract elements from a composite image by providing a Sprite Editor for the purpose. For example, the image could contain component parts of a single character, as with a car whose wheels move independently of the body.

Sometimes a sprite texture contains just a single graphic element but it is often more convenient to combine several related graphics together into a single image.
