Graphical Terrain Previewer converts the elevation value with gray scale gradation. This improves the terrain visibility of Random Gen World Previewer, in exchange for biome visibility.
There are 3 modes available
Map actual in-game world. Show elevation as gray scale gradation.
-28 is BLACK, 190 is WHITE.
Same as WorldPreview. But show the area out of -28 to 190 as RED.
Show elevation as monotone gradation.
-1 is BLACK, 1 is WHITE.
NOTE:
This is intended only for Random Gen World Previewer.
Don't run New Game or Continue Game.
