Direct3D can blend as many as eight textures onto primitives in a single pass. The use of multiple texture blending can profoundly increase the frame rate of Direct3D applications. Applications employ multiple texture blending to apply textures, shadows, specular lighting, diffuse lighting, and other special effects in a single pass.
To blend multiple textures, applications assign textures into the set of current textures, and then create blending stages. The topics in the following list present information on how these steps are accomplished.
