Problem with shaders : Opaque and transparent

First sorry for my english.

I have two objects that have to be transparent with “alpha” 0.5f. With the “Standard” in mode opaque I have the silhouette of the cut or intersection of the two objects.

When Ichange the shader to any transparent way, this intersection desapear and there is no way to distinguise the points or way in wich the objects cut.

Are there any kind of tranasparent or fade shader to do this or I have to create a new one? in wich way?

This is a limitation of real time rendering.
