Ich habe einen Unity-Shader für 2D-Sprites glänzend:Unity glänzend Shader-Overlay 2D-Sprite
//Kaan Yamanyar,Levent Seckin
Shader "Sprites/ShinyDefault"

}Aber mit diesem Code die Pixel des 2D-Sprite hinter diesem glänzenden Shader sind. Jetzt möchte ich nur dieses Shader-Overlay-Sprite zeigen und alle Pixel im Sprite werden nicht angezeigt.
Wie kann ich das tun?
