AssetPostprocessor Class

Scripting > Editor Classes > AssetPostprocessor

AssetPostprocessor lets you hook into the import pipeline and run scripts prior or after importing assets.

Note: This is an editor class. To use it you have to place your script in Assets/Editor inside your project folder. Editor classes are in the UnityEditor namespace so for C# scripts you need to add "using UnityEditor;" at the beginning of the script.

This way you can override default values in the import settings or modify the imported data like textures or meshes.
