AssetPostprocessor.OnPreprocessModel()

설명

Add this function to a subclass to get a notification just before a model (.fbx, .mb file etc.) is imported.

This lets you control the import settings through code.

using UnityEngine;
using UnityEditor;

// Disable import of materials if the file contains
// the @ sign marking it as an animation.
public class Example : AssetPostprocessor
{
    void OnPreprocessModel()
    {
        if (assetPath.Contains("@"))
        {
            ModelImporter modelImporter = assetImporter as ModelImporter;
            modelImporter.materialImportMode = ModelImporterMaterialImportMode.None;
        }
    }
}
