How to do it...

Let's learn how to use packed textures by entering the code shown in the following steps:

  1. We need to add a few properties to our Properties block. We will need five sampler2D objects, or textures, and two Color properties:
Properties 
{ 
 _MainTint ("Diffuse Tint", Color) = (1,1,1,1) 
     
//Add the properties below so we can input all of our    textures 
  _ColorA ("Terrain Color A", Color) = (1,1,1,1) 
  _ColorB ("Terrain Color B", Color) = (1,1,1,1) 
  _RTexture ("Red Channel Texture", 2D) = ""{} 
  _GTexture ("Green Channel Texture", 2D) = ""{} 
  _BTexture ("Blue Channel Texture", 2D) = ""{} 
  _ATexture ("Alpha Channel Texture", 2D) = ""{} 
  _BlendTex ("Blend Texture", 2D) = ""{} 
} 
As always, remove the properties we are not using from the base ...
