For previewing and creating terrains imported from other terrain editing/creating packages
This script was written to speed up working with other packages to create grayscale images to be used as height or displacement maps in max.
It lets you change the resolution (detail) and the height of the terrain in max.
When you save the height-map in the other application - click on 'update' and the mesh will be updated.
You can adjust the height of the terrain and convert the terrain into a mesh when you are happy with it
