What is the difference

The video effectively uses a clear visual demonstration of a 3D model and its associated normal maps to explain a technical concept. The creator's direct explanation and the on-screen text break down the information in an easily digestible format, making it valuable for aspiring 3D artists.

The video explains the difference between a normal map and a world space normal map, using a dragon head model as an example. It highlights how normal maps show surface details, while world space normal maps indicate the direction of faces relative to the world, which is useful for applying effects like dust layers.
