three.js - 影を制御する Three.js

Question

THREE.js で影を制御できません。まず、シーンの影が暗すぎます。私が読んだことによると、現在のバージョンの three.js では使用できなくなった、shadowDarkness プロパティがありました。誰かが回避策を知っていますか?

また、添付の画像では、「背面」ジオメトリは座席の影の光を遮っていませんが、球体 (cubeCamera) の反射でスツールの背面を見ることができます。誰もそれを修正する方法を知っていますか?

補足: chrome は、「Uncaught TypeError: Undefined のプロパティ 'visible' を設定できません」というエラーを表示します。

 frameMesh.visible = false;
    cubeCameraFrame.position.copy(frameMesh.position);
    cubeCameraFrame.updateCubeMap(renderer, scene);
    frameMesh.visible = true;

私のコードの一部。それは何らかの形で影に影響を与えているでしょうか？コードのその部分にコメントしても、スツールフレームの「反射」の外観にはほとんど影響しません。しかし、それはもはや球に反映されません。どんな助けでも大歓迎です。
