Using the Unity Sprite Editor

Here I will demonstrate how to use the sprite editor to slice up an image into individual sprites. The image below is one .PNG file meant to be used as terrain tiles:

After importing it into Unity, we need to change the sprite mode to Multiple. . If you want to learn about some of the other settings look here: Unity — Manual: Texture Import Settings (unity3d.com).

Next, we open the Sprite Editor and slice.

You can see in the image above that the sprites were not sliced correctly. The individual tiles are supposed to be 16X16 pixels. Because of the way the image is set up, automatic sprite slicing will not work.

We will need to manually slice them by cell size, specifying that each tile should be 16 X 16 pixels:

Below you can see what the finished product looks like in the project panel:

Each terrain item is one of the tiles from the greater image.

That’s all it takes to slice an image using Unity’s Sprite Editor.
