how terrain erosion works?
what the parameters does?

Im not to sure but i advise not to use it when objects are already on the map cuz it causes them to float.
If they float there´s always that option where you can set all objects back to 0 level with only one push of a button.

#1 What button is that? #2 I don't want all my objects back to 0 cuz some of them don't work right when they are on 0 like dum poublohi 5 and Domek_Radnice. And sometimes i like having trees partly in the ground.
That option is in object manager.

I've only managed to get a sketchy feel of the thing but here's some tips:
nGens: 0-128. Since the ofp map square is 128x128m wide (wasn't it http://forums.bistudio.com/oldsmileys/rock.gif ), I presume this is how many smaller plains you fit into it in terrain detail levels... in buldozer the squares show up as rough 50x50, it's totally different ingame.
WashCoef: 0-1. The first eroding factor. I use very minimal values, and this has 0.006. Don't know what exactly this does.
SedimCoef: 50-300. This factor does very little afaik (with settings I use). I can even use 300 and I don't see any difference.
SedimBase: 0-1. Perhaps the most important factor. This determines the hardness of the surface. I use 1 to achieve minimal height alteration.
SedimEff: 0-1. Almost same as above afaik. I use 0.9
InitRain: 0-1. The most eroding factor with the last one. I use 0.006 to achieve very round shapes together with the beforementioned settings.
SteadyRain: 0-1. Hard to tell the difference between this and the above rain. Might be even harder eroding. I use 0.001.
Tick on finalblur and you'll certainly get round shapes, but also lose almost all details you've possibly made into an ASE map.
Take into account the area you choose. Selecting also water makes a difference, the coastline might widthraw more inland with it selected.
The best way to use terrain erosion is by using it to just smoothen out the whole area at once after importing an ASE.
Open up a new image in a photo program. Fill it with black and them paint your island with black and white (white is high).
Work on it with Photoshop filters like artistic/smudge stick or similar filter in another program. It adds somewhat natural strokes to the surface.
