As you can see above the smoother gradient makes the terrain looks allot more natural. It has been commented that the staired terrain looks cool, like contour farming, and perhaps it does in unique circumstances but it will not work for the terrain in general. Despite this success the loading/saving time and file size has been affected even more than predicted. Huge Height Map files and long loading times are not acceptable.
- Split the terrain over many files and load the segments coming into view on another thread
- Store the terrain in the original .raw file and use some logic to smooth the vertices's
