    An grass ( need alpha test ) using myself shader, it's shadow hasn't alpha test. ( left of the picture)
    But The grass using the standard shader ( Rendering Mode: Transparent ), the shadow is correct, it's alpha test. ( right of the picture)

    You need just need to add a fallback to a built-in transparent shader. If that doesn't work for some reason, you can add the parameter "addshadow".
