    Hello everyone, maybe someone can help me figure this out.
    The Unity documentation claims that
    >> AlphaTest is a separate queue from Geometry one since it’s more efficient to render alpha-tested objects after all solid ones are drawn.

    Why is that? Since using alpha test prevents us from benefiting from early-z rejection wouldn't it be more efficient to draw all alpha-tested objects first?
