as far as how terrains are seeded, oceans, land masses and mountains are determined strictly by a height map, so everything below x is ocean, everything above y is mountains. rivers are created in a similar manner. the other terrains are sort of 'grown' in the space in between.

try using the tlevel command

the default is tlevel: mountain 120;

so try using a lower number

impassable terrains, border mountains and the other dom3 terrains are something that i intend to work on after i get the sprite functionality in.

well i'm glad that the thing is working, though i'm quite annoyed that it can't be simply copied to another machine.
