Thanks Watcher for this piece of info!
....Also using the map builder tool (or mode) raising terrain is possible with more accuracy al lower heights than at higher. By the way, do you have this "map builer tool" already?

Lowfighter, don't have the "map builder tool", do you have a link to where I may find this. At the moment I am using Landserf for working with SRTM and DEM data, and Gimp for all other work. Landserf is free and can be found at: http://www.soi.city.ac.uk/~jwo/landserf/

Is there a tool yet for working with map_c files and decoding actors.static? I have tried to manually split and join map_c files into 32x64 pixel blocks and rearrange them, but the end result is poor.

I am still curious why Photoshop "corrupts" the shape of the test slope with bumps and ridges when dither is off, yet Gimp gives a smooth slope. Have you noticed any other problems when using Photoshop to modify map files?

Cheers
