FT does produce Heightmaps (although i do not believe that these are 16 bit). As I said earlier you can generate a heightmap by going to: Tools/Show Other Shader/Bump Map.

FT can also produce normal maps (which is very cool) by using: Tools/Show Other Shader/normal map.

FT can also export as a CC drawing which in turn can be saved as a DXF or DWG file which is useful for people using vector graphics programmes.

From that point of view FT/CC is brilliant.
