First off, hightmaps are not good. Second, I found that
good semi-good hightmaps are not black and white. Like... grayscale clouds kind of. Third, a program called eathersculptor can export terrain models and hightmaps and as .obj files. If i ever use a hightmap i make it with eathersculpter.
http://www.earthsculptor.com/index.htm thats it's webpage. the problem is it makes terrain good for HUGE maps, landscapes for renders, and skyboxes. Forth, 6.5 is not a good rating, Good maps get an 8 or above mostly. There are many exceptions though.
