I used the heightmap to produce the terrain in cryengine. I edited it
using the terrain tools until I had the right scale and layout I wanted. This
didn't take too long and allowed me to jump into the map at any time to check
things. I also created a few solids in CryEngine, which are basically just primitives
used to block out the geometry.
Because my level was based in a gorge, the players view was limited, and
there was a lot of unused terrain which the player would never see. So i decided
to export the terrain and solids into 3ds Max and retopologize. This also
didn't take too long, and as everything would eventually be replaced by rock
assets anyway, this wasn't a problem.
