Question: Some material types may include normal map textures. What does a normal map achieve?

1. It programmatically reduced the polycount of your meshes.
2. It displaces mesh geometry with extrusion and bevels to generate higher-poly versions.
3. It creates the appearance of surface detail on mesh - like bumps, dents, and scratches
4. It is a level-of-detail system that progressively reduces a mesh?s polygons as a scene camera moves farther away from it

Answer: The correct answer of the above question is Option C:It creates the appearance of surface detail on mesh - like bumps, dents, and scratches
