How to apply a transparent texture I have a transparent texture and I can't figure out how to apply that transparency to the object. 



As you can see, the texture in the bottom right is transparent in places and solid in others.
But in render view the texture is just black.



You can see it better here.
Where Alpha = black = 0, the Transparent shader is used ; when alpha = white = 1, the Diffuse is used ; for intermediate value, they are mixed.
