如何将MixedReality-ToolKit实现到现有的HoloLens项目中？

Question

我正在从这个项目扩展Unity 2017.4.21f中Hololens的VideoCaptureExample：https://github.com/VulcanTechnologies/HoloLensCameraStream

现在我必须从我的Canvas控制ScrollView和Buttons所以我需要来自MRTK的Gaze-Function。一旦我尝试从这个页面实现unitypackage：https://github.com/Microsoft/MixedRealityToolkit-Unity/releases for 2017.4.2.0它向我显示了许多C ++异常，而我甚至没有使用该包中的任何内容：

Exception thrown at 0x76EDF2B2 (KernelBase.dll) in HoloLensVideoCaptureExample.exe: WinRT originate error - 0x80131534 : 'System.TypeInitializationException: The type initializer for 'WinRTBridge.WinRTBridge' threw an exception. ---> System.TypeInitializationException: The type initializer for 'WinRTBridge.TypeInformation' threw an exception. ---> System.IO.FileNotFoundException: Could not load file or assembly 'GLTFSerializationUWP, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'. The system cannot find the file specified.

我已经尝试检查播放器设置并对其进行了研究，我真的陷入了这个问题。以下是Unity的播放器设置：

Answer 1

我刚拿了那个版本的MRTK和最新的HoloLensCameraStream源代码。仅运行HoloLensCameraStream示例会产生一些C ++ TypeLoadExceptions;添加MRTK 2017.4.2.0并没有增加它们，也没有看到GLTFSerializationUWP相关的类型加载。相反，我确实在输出中看到GLTFSerializationUWP已成功加载，因为它现在作为包含MRTK的一部分包含在您的项目中。

两种选择：

• 从Unity生成新的UWP构建到空文件夹
• 尝试更新到不再具有GLTFSerializationUWP.dll引用的较新MRTK

希望有所帮助！
