Hi Christoph, Are your elevation and imagery in the same coordinate system? It's been awhile since I've looked at VPB, but if I recall correctly, the last input file on the command line is used to determine the coordinate system of the output database. So, if someGeoTiff_Height is in a geodetic projection and someGeoTiff_Texture is in a UTM projection, the first command will produce a database in geodetic and the second command line will produce a database in UTM.
VPB should scale height values appropriately (at least it was at one point) if you are producing a geodetic database, but this is one explanation as to why your output would be different depending on the order of your command line arguments. Good luck!
