エクスポート時にブレンドシェイプを含むパーツが消える

[sorogonliy]

モデルのエクスポート時にブレンドシェイプを含むパーツになにか問題があるようでエラーになります。

ご報告ありがとうございます。
出来ればUnityのバージョン、使用したUniVRMバージョン、再現方法などを教えて頂けると助かります。

追記
OS:Windows10 64bit
Unity:2018.4.20.f1
UniVRM0.55.0

[sorogonliy]

再現方法
①ヒエラルキー上に置いたモデルのプレハブアセットをクリック
②VRMタブからExport humanoidをクリック
③VRM Exporterウィンドウに必要事項を記載の上、Forse T PoseとPose Freezeのみにチェックを入れた状態でExportを押すとエラー

補足
Pose Freezeにチェックを入れない状態だと一応Exportされるが、二度目のExport時にPose Freezeにチェックを入れると同様にエラー発生。

[sorogonliy]

タイトルの説明に少し誤りがありました。
実際には「エクスポートされたVRMにブレンドシェイプを含むパーツが消えている」のではなく、そもそもこの状態ではエクスポートはエラーで実行されず、その代りヒエラルキー上に出てきたモデル名(normalized)という新たなプレハブにブレンドシェイプを含むパーツが反映されていないという現象が起きています。モデル名(normalized)のブレンドシェイプを含んでいたパーツはSkinned Mesh Rendererごと消えている状態です。

情報ありがとうございます、調査してみます。

ArgumentException: Blend shape frame weight must be greather than previous frame weight

とエラーが出ているため、おそらくMesh = Face.baked にある BlendShapeName = 上のブレンドシェイプに複数フレーム登録がされており、Normalize時にうまく変換が出来ていないようです。
Normalize処理が複数フレームブレンドシェイプに対応していなかったため、いったんこの部分の修正を行います。

[hiroj]

Forse T PoseとPose Freeze時に複数フレーム登録されているBlendShapeがコピーされるように修正を入れました #410.
よろしければ動作確認をしていただけると助かります。

[sorogonliy]

返答が遅れてしまい申し訳ございません。
当方、素人のため基礎的なことをお聞きしたいのですが上記の修正を適用するには #410 のページのFiles changedの内容をBoneNormalizer.csを編集し反映すればよいのでしょうか。
Files changedの赤い行を削除し、そこに緑の行を挿入するというやり方で大丈夫でしょうか。

[PoChang007]

はい、その方法は大丈夫ですが、
オススメのやり方は：
このリポジトリをダウンロードする。
もしくはこのリポジトリからプルする。
ダウンロードしたフォルダをUnityでOpenする。

試して見ましたが上手くいかないようでした。

v56.2パッケージ使ってもインポートうまくいかなかったの場合は、インポートうまくいかなかったのモデル共有することは可能ですか？

私たち調査してみます。
