25 Surface Shaders and Texture Mapping How to do it... There are two types of variables in Cg: single values and packed arrays. The latter can be identified because their type ends with a number such as float3 or int4. As their names suggest, these types of variables are similar to structs, which means that they each contain several single values. Cg calls them packed arrays, though they are not exactly arrays in the traditional sense. The elements of a packed array can be accessed as a normal struct.

This will give us the four blending textures that we can use to direct how the color textures will be placed on the object surface. We can use very intricate blending textures to create a very realistic distribution of terrain textures over a terrain mesh, as seen in the following image: 47 Surface Shaders and Texture Mapping 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) = ""{} } 2.

This is used for most objects. Opaque geometry uses this queue. 2000 AlphaTest Alpha-tested geometry uses this queue. It's different from the Geometry queue as it's more efficient to render alpha-tested objects after all the solid objects are drawn. 2450 Transparent This render queue is rendered after Geometry and AlphaTest queues in back-to-front order. Anything alphablended (that is, shaders that don't write to the depth buffer) should go here, for example, glass and particle effects. 3000 Overlay This render queue is meant for overlay effects.
