Bump Maps (or Normal Maps) are a graphic effect that creates a visual illusion of bumps and dents on the mesh without adding actual details to it. If a bump map is done properly, it can add more realism to even the most low polygon mesh.
However, some objects in Sims 3 can look good without a bump map, so use it only if needed as it can heavily affect the package size.
