First of all.
Thank you to "Lowkee33", for providing lots of information on how to mod terrains from my questions and also from his tutorials.

& Thank you to "Orange" For his PyreneanTerrainMod.
Note- In the following Update I will be talking out of my ass. This is probably the most basic terrain modifying there is, yet I try to sound professional and smart. Please ignore that fact. I'm just trying to be nice and let everyone know how I got my terrain. Thanks!
So, recently I have found a great new terrain mod for Nouadhibou. Orange's Pyrenean Terrain Mod.But one problem. I have a desert region. However, I really love the textures @ sea-level. Solution, make those texture appear everywhere! I used pretty much this same thing to get my terrain for Lemsid, but with a different terrain mod.
So as I put Orange's terrain mod in, The textures at the sea are really nice. A very detailed and beautiful sand. However, higher elevations make grass. And this is a desert. Grass is a no-no.
So, there is a simple way to fix this!
I opened the program that reads living I's.
And then I opened the terrain mod file.
Went to the "Exemplar File"
Went to "Temperature Range Factor" and then "edit properties",
And changed the value from .33somthing, to a very high number. (20)
Opened SC4 and....
Whee. The textures are sandy from Sea-Level to the mountain tops!
I used a similar method to get my terrain for the region of Lemsid. (In the last update) Using Heblem's Yucatan terrain mod, and making it so that yellowish grasses at high altitudes appear at sealevel. Replacing the desert textures there.
I Hope this can help anyone out there trying to make terrain mods. You have to start with the simplest stuff, to move on to more advanced things.
