The question may be 20 "what?" on your image. Depending of your software and the kind of color you choose, it can be counted in percent or in 0-255 scale.
What I did when I encountered the same problem was setting the terrain in world, saving the height map and checking the value. If I remember well, 20meters ended up to be something around 16% grey (which does not find any of the two hypothesis above) I didn't have the curiosity to match the result with OpenSim settings about minimum and maximum terrain height. This could be the clue. -- http://www.speculoos.net/ secondlife://speculoos.net:8002/ Speculoos, the belgian cookie-flavored metaverse Le 6 mai 2012 à 16:00, Len W.
