Bump Maps A Bump map is an older type of map that create fake detail by giving an illusion of depth on the surface of a model using a very simple lighting trick. You don't get any additional resolution added to a model as a result of bump mapping. Bump maps are typically greyscale images that are limited to 8-bits of colour information. This tells the 3D software whether it is up or down. Bump maps are great for creating tiny details on a model such as wrinkles on skin and because the detail they create is fake the silhouette of the geometry that the bump map is applied to will always be unaffected by the map. Normal Maps Normal maps can be referred to as a newer better type of bump map, as with bump maps what you need to know is that the detail they create is fake and there is no additional resolution added to the geometry. A normal map creates the illusion of depth detail on the surface like a bump map however it does it differently. A normal map uses RGB information that ...
