Description

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; } } }
