Surface Shaders and Texture Mapping

In this chapter, we will explore the topic of Surface Shaders in greater detail than in the previous chapter. We will start from building a very simple matte material and end with holographic projections and the advanced blending of terrains. We will also see how you can use textures to animate, blend, and drive any other property that they like.

In this chapter, you will learn about the following methods:

• Diffuse shading
• Accessing and modifying packed arrays
• Adding a texture to a shader
• Scrolling textures by modifying UV values
• Creating a shader with normal mapping
• Creating a transparent material
• Creating a Holographic Shader
• Packing and blending textures
• Creating a circle around your terrain
