This is my first scene with textures:

And here is the file:
http://elgastro22.free.fr/temp/Textures.tgdI only put what I have understood, that is to say:
-A default "Power fractal" terrain
For the shaders:
-Colour (white for snow, green for grass...esay to understand!)
-Coverage
-Fractal breakup value (around 0.5 generaly)
-Maximum/minimum altitude
-Maximum/minimum slope
SO: what should I first change then to have better textures?
