GRHMEdit (GeneRally HMap Editor) by Mlynki
This is probably most advanced Hmap editor in GeneRally. It's made by Mlynki (mlynki at gmail.com). The tool is free.
Details about the tool:
It should run fine on up to Windows 10 at least (runs on mine anyway).GeneRally HMap Editor is a height map editor for the game GeneRally. There is an original track editor for the game which is good, but limited when it comes to terrain height map editing. So I wrote a program for this specific purpose. It works in full 3D and since I added various functions to it it is also useful for other things apart from height map editing.
