Normal Mapping in 3D graphics development is the process of using an RGB color-map to create a three-dimensional relief on a two-dimensional plane. The source for the normal map in blender can either be a texture already installed in Blender, or using an external picture-file (.jpg, .jpeg, .bmp, and so on) and loading it as a normal map.
How to bake a texture to its UV-mapped texture. This can be used to emulate the effects of lightening, texturing and other effects to make your object look as it dose in a render inside blenders game engine. These UV textures can also be exported with the model and be used in 3d games made with other applications as well.

Blender's bump map is one of the ways that you can make the images in your scene more exciting and realistic. The goal of this video is to show how bump maps do this. In keeping with the October Halloween mood, we'll start with a jpeg image of pumpkins.
