In this Cinema 4D tutorial we will go over the uses of Bump and Normal Channels. The Normal Channel is relatively new in Cinema 4D. Normal Maps have been used in the gaming industry for years because they render fast in real-time game engines. They essentially do the same thing, giving surface detail via grayscale or RGB maps to emulate detail that may be too fine to model. You can use a grayscale bump map in Cinema 4D in conjunction with the Normalizer Shader.
On objects such as slices of fruit, using Flat Projection of a texture with a bump or normal map is a great way to quickly add detail to objects with fine detail in very short deadlines. Keep these techniques in mind when scheduling and budgeting a project so the project in comes in on time and on budget.
