将此函数添加到子类以在运行纹理导入器之前收到通知。
这允许你为导入设置设置默认值。
如果你想更改纹理的压缩格式，请使用此回调。
using UnityEngine; using UnityEditor;
// Automatically convert any texture file with "_bumpmap" // in its file name into a normal map.
class MyTexturePostprocessor : AssetPostprocessor { void OnPreprocessTexture() { if (assetPath.Contains("_bumpmap")) { TextureImporter textureImporter = (TextureImporter)assetImporter; textureImporter.convertToNormalmap = true; } } }
