# Swapping Sprite Library Assets
|
|||
|
|
|
|||
|
|
If swapping each Sprite individually takes too much effort, you can instead swap the entire __Sprite Library Asset__ to another one containing alternate Sprites.
|
|||
|
|
|
|||
|
|
The following example shows how to switch from a Sprite Library Asset of color Sprites to another one containing identical Sprites but in grayscale:
|
|||
|
|
|
|||
|
|
<br/>__Left:__ Prefab with the colored Sprite Library Asset. __Right:__ Prefab with the grayscale Sprite Library Asset.
|
|||
|
|
|
|||
|
|
1. Create variants of your character artwork. In this example, a grayscale variant of the original artwork was created in Photoshop (or any other compatible image editor).
|
|||
|
|
|
|||
|
|
2. [Import](PreparingArtwork.md) both .psb files into the Unity Editor. Both become separate Prefabs in the Asset window.
|
|||
|
|
|
|||
|
|
3. Select the color Prefab and open it in the [Skinning Editor](SkinningEditor.md). Assign each Sprite of the character to a unique [Category](SpriteVis.html#how-to-create-a-category). It is suggested to name each __Category__ and __Label__ after the respective body part of the character. Apply the changes once you are ready, and exit the __Sprite Editor__.
|
|||
|
|
|
|||
|
|
<br/>The Category and Label names for the color Prefab.
|
|||
|
|
|
|||
|
|
4. Select the grayscale Prefab, and give its corresponding Sprites the same __Category__ and __Label__ names as the color Prefab.
|
|||
|
|
|
|||
|
|
<br/>Give the same Category and Label names to the grayscale Prefab.
|
|||
|
|
|
|||
|
|
5. Drag the color Prefab into the Scene view, and go to the root GameObject. The [Sprite Library component](SLAsset.html#sprite-library-component) is attached to the root GameObject and refers to the default __Sprite Library Asset__ that [Unity automatically generated](SpriteSwapIntro.html#how-unity-generates-sprite-swap-assets-and-components).
|
|||
|
|
|
|||
|
|
<br/>The color Sprite Library Asset.
|
|||
|
|
|
|||
|
|
6. With the Inspector window the color Prefab remaining open, go to the Asset window and expand the grayscale Prefab. Find the grayscale Prefab __Sprite Library Asset__ and drag it to the color Prefab‘s __Sprite Library Asset__ box, which replaces the color Prefab’s original Sprite Library Asset.
|
|||
|
|
|
|||
|
|
7. The Sprites of the color Prefab should have switched to their grayscale counterparts of the grayscale Sprite Library Asset.
|
|||
|
|
|
|||
|
|
<br/>The grayscale version of the color Sprite Library Asset.
