Caption: Figure 5.

Total spectrum, including transmitted and reflected emission from the BLR for two densities of the equatorial obscurer. The upper panel shows the the UV regions, and the lower panel shows the optical wavelengths. This figure shows how phenomena similar to changing-look AGN, in which a Seyfert I turns into a Seyfert II, would occur without changes in the intrinsic luminosity of the AGN.
