+# MigrateExporter
+
+- for runtime
+- Convert export vrm0 model directly to vrm1
+- input: vrm0 hierarchy + vrm1 meta
+- output: vrm1 binary
+
+## Detail
+
+最初に vrm0 モデルをエクスポートします。
+このとき後で vrm1 化する前提で通常とは別の設定にします。
+
+- 正規化しない
+- z+ もしくは 左手系のまま進める
+- divided vertex buffer(glb 向けに実装済み)
+
+得られた、vrm0 バイナリを migrate します。
+このとき、vrm1 の meta を外部から注入することで
+ユーザー入力無しでの migration で `完全な` vrm1 を出力します。
+
+結果に対して vrm1 バリデーション。
+
+- https://github.com/vrm-c/glTF-Validator/pull/1
+
+## Caution
+
+対象の `vrm-0.x` のライセンスを変更する権利が必要です。
