# Normal map Normal maps enhance the visual quality of materials by adding intricate surface details without increasing polygon count. They simulate bumps, scratches, or fabric textures without modifying the actual geometry. This effect relies on imported textures and is achieved by manipulating how light interacts with the surface, enhancing realism and depth. {% hint style="success" %} Any image can be uploaded and will be automatically converted into a specialized normal map {% endhint %} **Invert** option flips the texture’s details, which can help correct shading issues or adjust the perceived depth of the surface. {% embed url="" %} {% embed url="" %} --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
