Add this function in a subclass to get a notification just before animation from a model (.fbx, .mb file etc.) is imported.
借助此函数，您可以通过代码控制导入设置。
public class CreateAnimationClip : AssetPostprocessor
{
void OnPreprocessAnimation()
{
var modelImporter = assetImporter as ModelImporter;
modelImporter.clipAnimations = modelImporter.defaultClipAnimations;
}
}
