 # RuntimeLoad
 
+## Runtime Normalization (from `v0.92.0`)
+
+`VRM-1.0` は、ノードの `回転・スケールの削除` をしません。
+後方互換性のため、 `RuntimeLoad` 時に動的に `回転・スケールの削除` する機能を提供します。
+
+> `VRM-0.x` のエクスポート時の正規化に相当する処理です
+
+以下のように doNormalize に true を付与してください。
+
+```csharp
+using (var loader = new Vrm10Importer(vrm, 
+    // normalize option
+    doNormalize: true))
+{
+    RuntimeGltfInstance instance = await loader.LoadAsync();
+    return instance;
+}
+```
+
+## Migration(VRM-0 to VRM-1)
+
 `VRM-1.0` は、 `VRM-0.x` もロードできます。
 その場合、あたらしい meta への変換が発生し互換性の無い部分はすべて `不許可` の値になります。
 このため、変換前のライセンスにアクセスする API を提供します。
