1 | # UnityAnimatorChangeSprite
2 | This script will swap sprite of an active animator to another one with the same dimensions.
3 | 
4 | Just add this script to a gameobject with animator and change "swappedTexture" through script or in editor and place swappedTexture.shader into Resources/Shaders folder. Afterwards you can swap texture through the script with a SwapTexture(Texture2D _toWhat) function.
5 | This will make animation of characters with different clothes way easier. You can animate main character and swap his clothes on the fly
