Function

UsePass "Shader object name/PASS NAME IN UPPERCASE"
Inserts the named Pass from the named Shader object.

If the named Shader object contains more than one SubShader, Unity iterates over the SubShaders until it finds the first supported SubShader that contains a Pass with the given name. For information on how Unity determines whether a SubShader is supported, see Shader objects introduction.

If the SubShader contains more than one Pass with the same name, Unity returns the last Pass it finds.

If Unity does not find a matching Pass, it shows the error shader.
