blendshapebuilder's Issues

animationしているものの修正について

Timelineでanimationさせたobjectに対して　例えば（animationで変形が入った）キメのposeの顔を調整したい　場合にこのToolが使えるかなーと試してみたのですが　そもそもUnity上でanimationでobjectが変形したり元の位置から移動しているmeshに対してモーフターゲットを生成しても「objectの元の位置でanimation変形前の形状にしかモーフターゲットは生成できない」でしょうか
Unityの仕様な気もしているのですが…

Errors in Unity 2018

Unity2018系でツールが正しく動作しないエラーがあるようです。
2017系では正しく動作しているようです。

【事例1】

「頂点表示の際にメッシュが透明になり追従しない」問題がありました。

以下の条件下で発生：

Unity 2018.2.9f1　
SkinnedMeshのモデルで、"Vertex Tweaker"ツールを使用した場合
　なお、表示がおかしく操作しづらいだけで、ブレンドシェイプには影響ありません。

【事例2】

「"Vertex Tweaker"ツールが動作しない」問題がありました。

以下の条件下で発生：

Unity2018.3.0f2
"Vertex Tweaker"ツールのEdit Verticesボタンが反応せず、エラーを吐く
Mesh / SkinnedMesh どちらでも発生

以下コンソールのログとなります。

Todo for Next Release

Undo 履歴のメモリ使用量が大きすぎるのをなんとかする
現状全頂点の履歴を取ってるので、ポリゴン数多いモデルは一瞬でメモリを食い潰す。ZSTD とかで圧縮が手っ取り早い対処法、それに加えて変化があった部分だけ履歴を取るようにできれば理想。
ミラーリングの改良
現状位置と法線が全く同じ頂点があると高確率で関連性が崩れる。既にそれなりに手をつくして解決できないままだが、なんとかしたい。
-> モデルをバッサリ半分切り捨てて自力で作り直せば解決できるかも
ポリゴン単位の表示/非表示
京野さんから
Find Targets で候補を選択すると Blend Shape Builder ウィンドウが切り替わるのをなんとかする
旧バージョンから更新を忘れた部分。
MeshFilter + MeshRenderer を SkinnedMeshRenderer に変換する
もしくは blend shape は SkinedMeshRenderer じゃないと再生できないのを何らかの形でユーザーに伝える。情報源
Unity 2017.1 でコンパイルエラー
Normal: 自動計算がデフォルトなのはまずいかも
法線が手動で編集されたものかを判定して、そうであれば自動計算オフをデフォルトとできれば理想

Illegal mirroring vertices

On VertexTweaker window, set Move with "Soft Move".
Change Mirroring Direction to "Right To Left".
Move some vertices on right side, then you can see strange mesh on the other side.

macOS High Sierra 10.13.3
Unity Editor 2017.3.0f3
