yeah; those textures aren't tiling properly, that be ye olde problem there.

this is a great texture library; and aside from things i've downloaded from cgtextures and some others, i think you'll be able to find something you like in there.
my suggestions for getting a nice texture out of springmapedit...
- use as many layers in the script as you need; don't oversimplify
- for each layer, pick two textures... one that will be a "base color" like a dark mud or something like that that goes into your script, the other being a "highlight color", maybe some lighter mud or possibly grass...
- after the script is applied, for each level take your second texture and scrub it around over the first, in order to remove the look of tiling
you can look at "forgotten crossing" for example... i went a bit nuts with the texture scrubbing and added a wee bit too much contrast, but it's a good example of what im on about.
(otherwise its all good m8, heightmap looks fairly fun to play!)
