In the latest developmental build of L3DT Pro* I have added anti-aliased smoothing to the alpha map generator. The controls are much the same as with the texture map generator, which has had anti-aliasing for some time now.
The effect of alpha map anti-aliasing is shown in the image below. In the left half, anti-aliasing was disabled, and the alpha maps appear pixellated. In the right half of the image, 8x anti-aliasing was used, and the transitions from one land type to another appear smooth.
As should be expected, large anti-aliasing radii will result in longer calculation times. Consequently, this calculation is now on the list to be multithreaded.
Please let me know if you find any problems.
Cheerio,
Aaron.
* L3DT Pro 2.8 build 5, released on the 22nd of December 2009.
