1. Problem description
Recently, I found a problem when developing an HTC project. I can recognize the helmet in the editor, but after publishing, the helmet cannot be awakened after opening the program. The version is Unity2019.4.33, and SteamVR is the latest download from the store. Importing the SteamVR plug-in is to select the LegacyVR mode.
2. Resolution process
First rule out the problem of the connection line, because it is normal in the editor, check the Player in the ProjectSetting settings. Make sure that Virtual Reality Supported is checked and OpenVR is selected. As shown below:
Then select XR Plug-in Management and check OpenVR Loader. As shown below:
In this way, the helmet will be awakened normally after the release.
3. Summary
The Unity2019.3 version brings XR Plugin Management. At the same time, Valve will also use Unity’s XR SDK to open the Unity XR plug-in of the OpenVR protocol (supporting 2019.3 or later). That is to say, Unity’s native support for OpenVR will be after 2019.3 The version becomes a plug-in form.
XR Plugin Management: A package to simplify XR plugin management. Provides help and administrative functions for loading, initializing, setting up, and building support for XR plugins.
4. Chinese character bug problem
For example: fire robot.exe odd number of Chinese characters can not be awakened.
