How to achieve Toon shade on Terrain?
How to you set the terrain to have a toon/cel shaded effect on it?
You cannot unless you find the terrain shader in the unity contents folder, and change it to support toon shading. Your only other real option would be to use an image effect such as edge detect.
This might be pretty old but I figured it out
Shader "Hidden/TerrainEngine/Splatmap/Lightmap-FirstPass" {
Properties {
_Control ("Control (RGBA)", 2D) = "red" {}
_Splat3 ("Layer 3 (A)", 2D) = "white" {}
_Splat2 ("Layer 2 (B)", 2D) = "white" {}
_Splat1 ("Layer 1 (G)", 2D) = "white" {}
_Splat0 ("Layer 0 (R)", 2D) = "white" {}
// used in fallback on old cards
_MainTex ("BaseMap (RGB)", 2D) = "white" {}
_OutlineColor ("Outline Color", Color) = (0,0,0,1)
_Outline ("Outline width", Range (.002, 0.03)) = .003
_Color ("Main Color", Color) = (1,1,1,1)
_ToonShade ("ToonShader Cubemap(RGB)", CUBE) = "" { Texgen CubeNormal }
}

This is a slightly late response but actually, you can
change the first line of your toon shader code to the same name that the default terrain shader works and unity will use your terrain shader (your toon shader) instead of the default one. i.e.: the first line of your toon terrain shader should be:
"Shader "Hidden/TerrainEngine/Splatmap/Lightmap-FirstPass"
This might be a bit old but I actually figured it out.
Shader "Hidden/TerrainEngine/Splatmap/Lightmap-FirstPass" {
Properties { _Control ("Control (RGBA)", 2D) = "red" {} _Splat3 ("Layer 3 (A)", 2D) = "white" {} _Splat2 ("Layer 2 (B)", 2D) = "white" {} _Splat1 ("Layer 1 (G)", 2D) = "white" {} _Splat0 ("Layer 0 (R)", 2D) = "white" {} // used in fallback on old cards _MainTex ("BaseMap (RGB)", 2D) = "white" {} _OutlineColor ("Outline Color", Color) = (0,0,0,1) _Outline ("Outline width", Range (.002, 0.03)) = .003 _Color ("Main Color", Color) = (1,1,1,1) _ToonShade ("ToonShader Cubemap(RGB)", CUBE) = "" { Texgen CubeNormal } }
