Terragen 3 is built around a full planet model, allowing you to build whole worlds of realistic, detailed terrain. We haven't neglected the other end of the spectrum though; Terragen 3 is equally adept at depicting small-scale details, with displacement down to the centimeter level, and a detailed lighting model allowing realistic rendering of close-in scenes.
With both large and small-scale detail possible in the same scene, you can go from orbit to ground level seamlessly and easily. Forget clumsy or obvious cuts and other cheats, Terragen 3 gives you all the freedom you need to realize your vision.

Terragen 2 has been giving me incredible skies and environments for many years now. The team has taken an exponential leap in terms of photographic reality. I have done several projects with Terragen 2 where it has generated lighting and reflection HDRIs and those became the only light source in the 3D renders. With the ability to load georeferenced DEM data so easily and so accurately, guesswork is gone and you can concentrate totally on image fidelity. It's a piece of software I would not do without at this point. A serious primary asset in the tool belt.
