NDMFプラグインが動的生成したMeshSettingsでNullReferenceException

[kaikoga]

• NDMF プラグインから BuildPhase.Generating などで AddComponent<ModularAvatarMeshSettings>() する
• 動的生成した ModularAvatarMeshSettings の InheritBounds を ModularAvatarMeshSettings.InheritMode.DontSet などに設定する

Workaround

  var meshSettings = modularRoot.gameObject.AddComponent<ModularAvatarMeshSettings>();
  meshSettings.InheritBounds = ModularAvatarMeshSettings.InheritMode.DontSet;
+ meshSettings.RootBone = new AvatarObjectReference();
