I search now for quite a bit to say I realy dont know what to do.
What I try is to export the Heightmap of my Terrain (which I created in Terramonkey),
to recreate it in Blender and create a Model which fits into the terrain as a Ground (to also make it visible from bottom).
The forum helped me to get the HeightMap in Float format
Spatial terrainH = myHomeNode.getChild(0); Terrain helpT = (Terrain) terrainh ; float heightmapF = helpT.getHeightMap();
I know that their a Classes like HeightMap who help get Pictures into the Float format, but is this process also inverseable ? To get a Picture out of the Floats ?
Thanks in advance
