How two sided shader work ? Had I to use in the same way in Arnold 4 ?

I tried to just plug in the front and back connector, but I have only the front shader when I render

The Two Sided shader works fine for me with the latest release of MtoA.

What are you rendering? Could it be that the normals are facing in the wrong direction?

That's it, thank you.

I forgot I extruded the mesh and all the Normals are in the same orientation.
