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.
In a production pipeline AssetPostprocessors should always be placed in pre-built dll's in the project instead of in scripts. AssetPostprocessors change the output of imported assets, thus a compile error in one of the scripts will lead to assets being imported differently. This can be a severe issue when working in a production pipeline. By using dll's for AssetPostprocessors you ensure that they can always be executed even if the scripts have compile errors. This way you can override default values in the import settings or modify the imported data like textures or meshes.
