AssetPostprocessor lets you hook into the import pipeline and run scripts prior or after importing assets.
During model import the functions are called in the the following order:
OnPreprocessSpeedTree and OnPostprocessSpeedTree are called on SpeedTree assets (.spm file) the same way as OnPreprocessModel and OnPostprocessModel, except that the assetImporter type is SpeedTreeImporter.
| assetImporter | Reference to the asset importer. |
| assetPath | The path name of the asset being imported. |
| context | The import context. |
| GetPostprocessOrder | Override the order in which importers are processed. |
| GetVersion | Returns the version of the asset postprocessor. |
| OnAssignMaterialModel | Feeds a source material. |
| OnPostprocessAllAssets | This is called after importing of any number of assets is complete (when the Assets progress bar has reached the end). |
| OnPostprocessAnimation | This function is called when an AnimationClip has finished importing. |
| OnPostprocessAssetbundleNameChanged | Handler called when asset is assigned to a different asset bundle. |
| OnPostprocessAudio | Add this function to a subclass to get a notification when an audio clip has completed importing. |
| OnPostprocessCubemap | Add this function to a subclass to get a notification just before a cubemap texture has completed importing. |
| OnPostprocessGameObjectWithAnimatedUserProperties | This function is called when the animation curves for a custom property are finished importing. |
| OnPostprocessGameObjectWithUserProperties | Gets called for each GameObject that had at least one user property attached to it in the imported file. |
| OnPostprocessMaterial | Add this function to a subclass to get a notification when a new Material is created during an import of a ModelImporter. |
| OnPostprocessMeshHierarchy | This function is called when a new transform hierarchy has finished importing. |
| OnPostprocessModel | Add this function to a subclass to get a notification when a model has completed importing. |
| OnPostprocessPrefab | Gets a notification when a Prefab completes importing. |
| OnPostprocessSpeedTree | Add this function to a subclass to get a notification when a SpeedTree asset has completed importing. |
| OnPostprocessSprites | Add this function to a subclass to get a notification when an texture of sprite(s) has completed importing. |
| OnPostprocessTexture | Add this function to a subclass to get a notification when a texture2D has completed importing just before Unity compresses it. |
| OnPostprocessTexture2DArray | Add this function to a subclass to get a notification when a texture2DArray has completed importing just before Unity compresses it. |
| OnPostprocessTexture3D | Add this function to a subclass to get a notification when a texture3D has completed importing just before Unity compresses it. |
| OnPreprocessAnimation | Add this function to a subclass to get a notification just before animation from a model (.fbx, .mb file etc.) is imported. |
| OnPreprocessAsset | Add this function to a subclass to get a notification just before any Asset is imported. |
| OnPreprocessAudio | Add this function to a subclass to get a notification just before an audio clip is being imported. |
| OnPreprocessCameraDescription | Add this function to a subclass to receive a notification when a camera is imported from a Model Importer. |
| OnPreprocessLightDescription | Add this function to a subclass to recieve a notification when a light is imported from a Model Importer. |
| OnPreprocessMaterialDescription | Add this function to a subclass to recieve a notification when a new material is created during the import of a ModelImporter. |
| OnPreprocessModel | Add this function to a subclass to get a notification just before a model (.fbx, .mb file etc.) is imported. |
| OnPreprocessSpeedTree | Add this function to a subclass to get a notification just before a SpeedTree asset (.spm file) is imported. |
| OnPreprocessTexture | Add this function to a subclass to get a notification just before the texture importer is run. |
