スクリーンショットを撮るときに問題があります。あなたがツタンツと一緒に従っている場合は、http://doc.babylonjs.com/tutorials/render_scene_on_a_pngで1行しか表示されていないことがわかりますBABYLON.Tools.CreateScreenshot(engine, camera, size);BabylonJSで黒いスクリーンショットを取得
サイズとカメラは変更可能な変数です。これを実装すると、黒のスクリーンショットが表示されます。最初に、ページがレンダリングされる前にスクリーンショットを撮っていたので、単純なループを追加して、スクリーンショットが実行される前にシーンがロードされるまで待つように警告ボックスを追加していたと考えました。しかし何らかの理由で私はまだ黒のスクリーンショットを取得しています。 はご入力いただき、ありがとうございます：D
