you have to change the material shader.


create for this a new material and select in the drop down from inside the standard shader transparent (normal is opaque)


now you can adjust transparency over the alpha color value

you have to replace the material. default mat. because there is only one material asigned to your mesh. you have to create a new material in your project folder with a right click and the select material. then you should be able to change the rendering mode.

then it should work.

might my answer here can help you!
