The material includes the "interior" block:

#declare MyMaterial = material {
   texture { ... }
   interior { ... }
}

#declare MyMesh = mesh {
   ...
   material { MyMaterial }
}


Unfortunately it doesn't work for meshes with multiple textures. Still, 
there should be a way to specify an interior for those as well, such as:

#declare MyMesh = mesh {
   triangle { ... texture { MyTexture1 } }
   triangle { ... texture { MyTexture2 } }
   ...
   interior { MyInterior }
}
