terrain shader

hi all
i get builtin shaders and see in that terrain shaders.
how can apply they to terrain?
thankful.

actually u cannot change directly the terrain material, but if u copy the terrain shader from the builtin shaders folder to your project u are actually overriding it, so u can change everything in it, but it must begin with

Shader "Hidden/TerrainEngine/Splatmap/Lightmap-FirstPass"

here is what u can achieve changing it
