/** Demo presets
@remarks The best way of determinate each parameter value is by using a real-time editor.
These presets have been quickly designed using the Paradise Editor, which is a commercial solution.
At the time I'm writting these lines, SkyX 0.1 is supported by Ogitor. Hope that the Ogitor team will
support soon SkyX 0.3, this way you all are going to be able to quickly create cool SkyX configurations.

我没有使用ExampleApplication框架或任何其他框架。我根据自己的需要改进了自己的小班。
我只能看到闪电，而且与演示相比，它们似乎太近了。此外，所有闪电的起源始终位于相机的顶部，随之移动。
我的场景中只有几个盒子和一个相机连接到其中一个。
我已将SkyX 0.3.1编译为单独的DLL，使用与调试conf'设置相同的boost和ogre库（与应用程序一样，全部作为调试）。
提及SkyX的调试输出如下：

Can't assign material _NULL_ to SubEntity of SkyXMeshEnt because this Material does not exist. Have you forgotten to define it in a .material script?
[SkyX] VClouds warning: unregistered camera registered, manual unregistering is needed before camera destruction
感谢。
答案 0 :(得分：0)
只需删除以下行即可解决问题。显然阴影不适用于SkyX。
sceneManager->setShadowTechnique(SHADOWTYPE_STENCIL_ADDITIVE);
您可以在SkyX初始化之后使用该行，但我不知道它是否有效。
