Ok so i've been following the Eriond tutorial and a few others to try and create a good looking hieghtmap and the terrain for it. However i'm just not good enough with these tools to create the needed effect.

In my world, i need the land layer to be 96+ and the sea to be 95 and below. But following the difference cloud method of creating this seems quite unreasonable, as it still tends to generate darkpatches. This heightmap is for a game, so there's no bending of the rules and i'm completely dumbfounded. Further, this map also has quite extensive mountains within it, and i cant seem to produce them without them looking too 'skinny' looking in GIMP or Wilbur. Another issue i've found in Wilbur, is that once i've imported my 2048X2048 image in, worked on it and re-exported it back to gimp, the image seems 'smaller', i think at some point of the export it was cropped or scaled down slightly, meaning it doesn't line up with the other files anymore, which i need it to. This could be alot easier if i knew the tools needed to do this but i don't, hence why i'm posting here.

The world i'm creating is a far more in detail, realistic and pretty version of the M&B: Warband world.
Here's a link to a google image of what im trying to replicate: http://img4.wikia.nocookie.net/__cb2...f_Calradia.jpg

I already have a outline of my map. And i know where mountains need to be, and plateau's, and there is also supposed to be a mountainous/highlander feel to the Yalen/Jelkala/Veluca area towards the SW.

So guys, any ideas? I got tired of lurking and figured the experts could help me out.
