Unity Development для HoloLens

Question

Я попытался разработать проект Unity с функцией двигателя Vuforia, который будет развернут на HoloLens. Краткое описание проблемы: не работаетЯ начал с создания очень простого проекта с камерой Vuforia AR и трехмерным кубом, помещенным в поле обзора, просто для его проверки. Это работает, чтобы представить его в превью Unity. Тем не менее, консоль Unity представляет ошибки, и ни программа Unity не работает на HoloLens, ни в качестве отдельного приложения в предварительном просмотре Visual Studio. Всегда возникают следующие ошибки:

DllNotFoundException: VuforiaWrapper.

В Visual Studio можно встроить отдельное приложение, которое отображает трехмерный куб, как и должно, но фон черный, камера не отображаетне работает (Razer Kiyo).

Я пробовал несколько версий Unity, включая версии LTS 2017 и 2018 и Visual Studio 2017 и 2019. Он не работает ни с одним из вышеперечисленных.

Импорт образца Vuforia Hololens в Unity разрушает проект и делает его некомпилируемым для КАЖДОЙ версии Unity, которую я пробовал, поэтому мне пришлось отойти от этого.

Есть ли у кого-то идеи, какрешить это? Кажется странным, что он даже не работает для такого простого проекта.

Ошибка DllNotFoundException: VuforiaWrapper указывает на то, что Unity пытается загрузить dll, но DLL, похоже, не существует в загружаемой папке.

Считывая ошибки, существует множество форм:

Fallback handler could not load library C:/Visual Studio Projects/UnityHololens2018_4_11VuforiaUpdate8_5_8_64_86_Test1/build/bin/UnityHololens2018_4_11TestVuforiaUpdate8_5_8_Data/Mono/VuforiaWrapper.dll

Вы проверили путь "C: / Проекты Visual Studio / UnityHololens2018_4_11VuforiaUpdate8_5_8_64_86_Test1 / build / bin / UnityHololens2018_4_11TestVuforiaUpdate8 для проверки наличия файлов? Похоже, что это сообщение об ошибке запускается локально на вашем компьютере, поэтому вы должны иметь возможность просто изучить каталог.

Обычно, когда я вижу dll не найдены ошибки, это потому, что мои dll плагина не настроены правильно,Просмотрите документацию плагина и дважды проверьте, что vuforia dll настроена для развертывания на архитектуре вашего компьютера и архитектуре HoloLens (то есть x86).
