Chapter 11. Developing Textures > Procedural Mapping

Procedural Mapping

Now that you've taken a quick look at Planar mapping and Render Bounding Box/Selected, let's investigate some of 3ds max 7's most useful map types: Noise and Falloff. These procedural maps are extremely versatile and can be applied in many situations to solve difficult texturing problems and to create quick and eye-catching texture effects.

Noise Mapping

Noise maps, which apply random marks to a surface, among the most widely used of procedural materials. Typically employed to reduce unwanted smoothness and add grain and grunge to a surface, Noise is also useful for creating lightning, fire, and water effects. Caustic patterns, the lighting effects caused by internal reflections and refractions in a body of water, can be made with a Noise map by loading it as a projector map in a spotlight or projector light. A Noise map employed as a Diffusion map in the 3ds max 7 Raytrace material is effective for “dirtying up” underlying textures. And Noise can break up tiled bitmap patterns that look too regular.
