Click on the Forum title, e.g. on the "Forums by Category" page, to read a sequence of postings to the Forum and its threads all in one page. If you are only interested in one thread or the thread following a specific posting, click the thread or the posting, which takes you to a smaller page, which contains only the part you are interested in and may be easier to navigate.
Messages are "chained" if there are only replies at the first level, i.e. 1/1.html, 1/1/1.html etc. In case of "chained" messages the message number is replaced by the icon and there is no indentation.

This is inconsistent; the unified model applies only to dielectric_dielectric surface types.
I suspect you want dielectric_metal. In that case, you should follow Example 5.9 in the Developers Guide:
Example 5.9. Dielectric metal surface properties defined via the G4OpticalSurface.
G4OpticalSurface* OpSurface = new G4OpticalSurface("name");
G4LogicalSkinSurface* Surface = new G4LogicalSkinSurface("name",volume_log,OpSurface);
OpSurface -> SetType(dielectric_metal); OpSurface -> SetFinish(ground); OpSurface -> SetModel(glisur);
G4double polish = 0.8;
G4MaterialPropertiesTable *OpSurfaceProperty = new G4MaterialPropertiesTable();
OpSurfaceProperty -> AddProperty("REFLECTIVITY",pp,reflectivity,NUM); OpSurfaceProperty -> AddProperty("EFFICIENCY",pp,efficiency,NUM);
OpSurface -> SetMaterialPropertiesTable(OpSurfaceProperty);
In general, please see the chapter on optical photon processes in the Developer's guide, in particular Figure 5.1
