Help with really shiny landscape?

So basically, I created a layered texture, to allow me to paint the landscape, and then I applied the material and… well… have a look at the picture…
[ATTACH=JSON]{“data-align”:“none”,“data-size”:“full”,“data-tempid”:“temp_125529_1513789308611_846”}[/ATTACH] so, that is my landscape, I do not understand why it is doing this, this is what the material looks like,

It is basically four copies of the basic “ground moss” material, but with different height maps and textures in each copy, because I have no idea what I am doing, so yeah, any ideas?
