The algorithm I use is pretty simple: I store
the heights, smoothen these outward onto neighbouring
nodes. To save parsing time, I leave out nodes which
are inside objects, which seems to produce the
error in this case: since the blocked nodes aren't
processed correctly (and thus aren't set to 0), they
add up and spill over later. Need to check more thoroughly
on that.
If you want, you can have a look at the source-code,
just head on to my homepage, in the downloads-
section.

Tim
