Proxy object was destroyed improperly! が発生する可能性があり、もし発生するとUnity再起動かNDMFのReimport以外で復帰不可

[Sayamame-beans]

詳細

確認済みの発生例

• Unity Package Managerからのインポート操作
• Tools/TextransTool/Debug/Migration/Migrate Project → Scene開き直しでYes

以下の警告が無限に発生する。

Proxy object was destroyed improperly! Resetting pipeline...
UnityEngine.Debug:LogWarning (object)
nadena.dev.ndmf.preview.ProxyObjectController:OnPreFrame () (at ./Packages/nadena.dev.ndmf/Editor/PreviewSystem/Rendering/ProxyObjectController.cs:146)

UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Tools/NDM Framework/Debug Tools/Show Preview Sceneで__NDMF Preview__Sceneを表示させると、中のオブジェクトが無限に再生成されることによりHierarchy上でオブジェクトが点滅している様子が見られる。

NDMF Previewを無効化することで警告の発生は抑制される(それはそう)
この警告が発生し始めた状態では、Sceneの再読み込みや__NDMF Preview__のRemove等では復帰できない。
Unityの再起動で復帰可能。

なお、本現象が発生している状態でNDMFを選択してUnity上でReimportすると

The following open scene(s) have been changed on disk:
 Packages/nadena.dev.ndmf/Runtime/___NDMF Preview___.unity

Do you want to reload the scene(s)?

を聞かれる。これをIgnoreし、その後Reimportが走ることでも直る。

環境

Unity: 2022.3.22f1
NDMF: 1.6.2

補足

TexTransToolを使用している場合、付随して以下のエラーも無限に発生する。

これ TTT がマイグレーションのとき、NDMF のシーンも巻き込んでやっちゃってるのが原因の一つだと思うからいじらないようにするのを検討してみる

あと付随のエラーはおそらくNDMF関係ない、TTT の方でシーンのリロードに耐えれないバグかも

[Sayamame-beans]

TTT関連の所はそうかも…
UPMのインポートでコケるのはどうでしょうね…(TTT無しで試すの忘れました…)
