editMAでコンストレインを書き出す

Last updated at Posted at 2024-12-05

さてアニメーションは書き出せたので、コンストレインも書き出したいですね。
コンストレインが書き出せるということは、アニメーションをベイクしなくても良いのでより選択肢が広がります。

書き出し

さて exportEditsコマンドを眺めてみます。

includeConstraints(ic)
さらに、書き出されるターゲット ノードに関連するコンストレイント関連のノードを含みます。

コンストレイント関連のノードというのが　？？ですが、多分これかなぁ。

同一リファレンス内のキューブからスフィアへparentConstraintを掛けました。

スフィアを選択して、書き出してみます。

import maya.cmds as cmds
exportFilePath = "D:/test/testConstraint.editMA"
cmds.exportEdits(
                            exportFilePath,
                            type = "editMA",
                            selected =True,
                            includeConstraints =True,
                            f =True
                        )

書き出されたファイルを眺めてみると、

  • コンストレインノードの作成
  • コンストレインノードとのコネクション

が記載されていますね。

読み込み

読み込みのコマンド自体は、アニメーションの読み込みと特に変わらないはずなのでそのまま実行してみます。

import maya.cmds as cmds
exportFilePath = "D:/test/testConstraint.editMA"

cmds.file(exportFilePath,
        type = "editMA",
        i =True,
        applyTo = "sampleAsset_v01RN",
        f =True
        )

無事コンストレインが再構築されました。
が、コンストレインノードが通常の挙動と違いworldに出てしまうのは少しきになりますね。

別の組み合わせ

同一のnamespace内でのコンストレイン情報の読み書きは出来ましたが、
別の場合はどうでしょうか。

シーンに追加したlocator1からconeに対してparentConstraintを掛けました。

これを書き出してみます。

import maya.cmds as cmds
exportFilePath = "D:/test/testConstraintCone.editMA"
cmds.exportEdits(
                            exportFilePath,
                            type = "editMA",
                            selected =True,
                            includeConstraints =True,
                            f =True
                        )

コンストレインノードとリファレンスされてるアセットの処理は一緒ですが、
locator1に関しては　<root>: がついてますね。
これは読み込ませるときに何か指定すべきか・・・

とりあえず読み込んでみます。

import maya.cmds as cmds
exportFilePath = "D:/test/testConstraintCone.editMA"
cmds.file(exportFilePath,
        type = "editMA",
        i =True,
        applyTo = "sampleAsset_v01RN",
        f =True
        )

問題なく生成されましたね。

さらに別の組み合わせ

さっきはシーンに追加したlocator1を使用しましたが、
新たに別のファイルをリファレンスして別のnamespace間でコンストレインした場合はどうでしょうか？

image.png

import maya.cmds as cmds
exportFilePath = "D:/test/testConstraint2.editMA"
cmds.exportEdits(
                            exportFilePath,
                            type = "editMA",
                            selected =True,
                            includeConstraints =True,
                            f =True
                        )

placeHolderが　<main>　と <sampleAsset_v01RN1> の2つに増えましたね。

		;
connectAttr "pSphere1_parentConstraint1.w0" "pSphere1_parentConstraint1.tg[0].tw"
		;
// End of testConstraint2.editMA

とくに編集することなく読み込んでみます。

import maya.cmds as cmds
exportFilePath = "D:/test/testConstraint2.editMA"

cmds.file(exportFilePath,
        type = "editMA",
        i =True,
        applyTo = "sampleAsset_v01RN",
        f =True
        )

別のnamespaceに適用させる必要が無ければ、このままで問題なさそうですね。
