読み込めない、存在しない項目があるようですが、Boothで購入したもののため、私ではいじるのは困難です。

[otoneco]

念のためキャラ名や著者等英語で統一しましたが、まだダメなようです。

[otoneco]

Sunaoshaderを使っているものがエラーを吐かれる傾向があるようです。

[esperecyan]

ご報告有り難うございます。
こちらはUniVRM-0.66.0へダウングレードした場合でも発生するでしょうか？
https://github.com/vrm-c/UniVRM/releases/tag/v0.66.0

[otoneco]

そもそもダウングレードができません
それをやるとVRM0が二度と表示されなくなります

[otoneco]

univrm同梱バージョンを変更or同梱なしをアップロードしていただけますでしょうか

[esperecyan]

最新安定版がUniVRM-0.79.0となったため、つい先日対応のための本拡張もv27.0.0へ更新しました。「Assets/UniGLTF」「Assets/VRM」「Assets/VRMShaders」を削除した上で、こちらをインポートしてお試しください。

[otoneco]

試してみましたが、やはりダメです
(前回のはモデル元の制作者様に直接変換していただいたため、他のモデルで試しました)

[esperecyan]

こちらはUniVRMのメニューからVRM化しようとした場合にも発生しますか？

上部メニュー → VRM0 → Export UniVRM-0.79.0

[otoneco]

いいえ、発生しませんでした。

もちろん表情やスプリングボーンはありません。
でも私はこれらを再設定する術を知りません。
テクスチャとか、ダイナミックボーンの変換とか、表情の登録方法とか、何一つ分かりません。
あなたのツールが必要です。

[esperecyan]

確認ありがとうございます。

エラーをこちらで再現できるunitypackage等を用意してもらうことなどはできますでしょうか？

[otoneco]

ごめんなさい。
再配布がNGなので厳しいです。

[otoneco]

https://booth.pm/ja/items/2615925
こちらで試しました
価格が高いので参考までにお願いします

https://booth.pm/ja/items/2361882
こちらでも試しましたが同じくダメでした

[esperecyan]

原因が分かりました。
アバタールート外を参照する不正なDynamicBoneが存在すると、上記と同様の例外が発生し、エクスポートに失敗するようです。

対策を行ったv27.1.0を公開しました。

ご報告有り難うございました。
