説明

AssetPostprocessor を利用すると、インポートしたパイプラインをフックし、アセットをインポートする前と後にスクリプトを実行することが可能になります。

During model import the functions are called in the the following order:
- OnPreprocessModel is called at the very beginning and you can override ModelImporter settings that are used for the whole model import process.
- After Meshes and Materials are imported, the GameObjects hierarchy is created from the imported nodes. Use OnPostprocessMeshHierarchy to change the hierarchy. Every GameObject that represents an imported node is given a corresponding MeshFilter, MeshRenderer, and MeshCollider component. Before assigning a Material to the MeshRenderer, the OnAssignMaterialModel function is invoked.
- After GameObject has initialized MeshRenderers and "userdata" exists OnPostprocessGameObjectWithUserProperties is called. That happens before children GameObjects are generated.
- アニメーション生成が以前に無効にされていなければ (ModelImporter.generateAnimations 参照)、スキンメッシュとアニメーションが生成されます。可能な場合は、アバターも作成され、ゲームオブジェクトのヒエラルキーが最適化されます。その後、OnPostprocessModel がルートのゲームオブジェクトのために呼び出されます。

assetImporter のタイプが SpeedTreeImporter であることを除き、OnPreprocessModelOnPostprocessModel と同様に、OnPreprocessSpeedTreeOnPostprocessSpeedTree が SpeedTree アセット (.spm file) に関して呼び出されます。

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.
