RemoveMeshByBlendShape がある Prefab Variant を編集すると PSUCREImpl で ANE が発生する

[kb10uy]

概要

• Remove Mesh by BlendMesh がツリー内にある Prefab Variant の編集中、ヒエラルキー内のデータが変更された時に以下の例外が複数回発生する。
  • 発生タイミングは Transform の値の変更や Component の追加・削除、Hierarchy 内の並べ替えなどほぼ全ての「変更」が対象っぽい？
  • 回数の基準は不明(この現象を確認した Prefab Variant では 7 回)。
  • Scene に配置したインスタンスでは発生しない。
