IMHO, there is little to choose between MultiGen & Corypheaus
for regular points'n'polygons modelling by hand. (I don't
know much about Terrex). Corypheaus is a bit cheaper. In the
end, it's largely a matter of taste.
For terrain, we didn't like *anything* that's out there and
wrote everything from scratch ourselves.

You might want to talk (offline) to my organization about
this. We have an extremely automated system that takes NIMA
data directly and makes complete Performer databases without
human intervention beyond the initial parameter tweaking. We
have used it to produce *huge* databases.
