在我的场景中实现子场景时，使用混合 2D 和 3D 时遇到一些问题。您可以通过单击链接查看问题。我正在使用 Interactivemesh-Modelimporter。

【解决方案1】：

您正在使用 3D 模型。

这意味着您的子场景需要一个 deapthBuffer 而不是您的主场景。这就是它适用于主要场景的原因。

改变

SubScene subScene = new SubScene (sub, 800, 600);

到

SubScene subScene = new SubScene(sub, 800, 600,true, SceneAntialiasing.DISABLED);

（SceneAntialiasing.DISABLED 或 SceneAntialiasing.BALANCED）
