Flex项目中的AIR Stage3D

我有一个Flex 4.5 AIR项目，我想创建一个使用stage3D的组件。我可以设法在Flash Player的Actionscript项目中获得三角形示例工作，但是我无法使用干净的Flex项目工作。它进入循环渲染，但其不可见：Flex项目中的AIR Stage3D

有什么想法？没有错误，它跟踪的OnRender，所以它只是不可见..：S

<s:Application .... backgroundAlpha="0"

固定它:)

在MX的Stage3D的好主意：集装箱比我不必着急MX ：应用程序与backgroundAlpha 0 ..是否有可能？谢谢。

我将PaperVision 3D改进为Stage3D ...因为它比Away3D更快..
