The general-purpose photoionization and radiative transfer code Cloudy, now includes the option of an internally generated diffuse continuum. This combined with the option of exposing simple slab model clouds to an external beamed or isotropic radiation field makes Cloudy a more versatile and realistic radiative transfer tool. Users may now choose these options for both "open” (single slab) and "closed” (two separated plane parallel slabs) geometries. The effects of these new options are demonstrated for the cases of: 1. a diffuse cloud PDR, 2. a compact H II region buried deep in a molecular cloud and 3. a dusty galaxy such as a ULIRG. We show sample calculations predicting the full emitted continuum for utilizing these new options and compare it to the results for the purely 1D case where all radiation is normally beamed through the clouds.
