Vuforia always set to OpenGL ES 2.0

By igrir on Tue, 08/06/2019 - 08:00

Greetings,

 

I am trying to implement Unity into React Native using a plugin from the following link https://github.com/f111fei/react-native-unity-view.

I successfully put Vuforia to be compiled alongside the app, but whenever I tried to compile the application Vuforia always set the rendering to OpenGL ES 2.0. Here's some log I gathered after I run the app:

It's really weird because I really need the app to run with Metal and I already forced the Unity Graphics API's into Metal.

Image removed.

 

I tried to run the app without using react-native way and the output was correct! It's using Metal for its rendering API. Here's some log from it:

My question is how does Vuforia detect the rendering API to be used at the initialization of the app? Maybe I could configure some specific file or settings on XCode to be read later by Vuforia framework and initialize its rendering API into Metal

 

Thanks

(Update)

I was reading how VuforiaUnityPlayer.h works, and looks like there's a method called initQCARiOS. I tried to find all of the scripts containg 'initQCARiOS' and suspect there's a part called Vuforia.UnityExtensions1.cpp which had this line:

 

Hey guys,

Did you found any solution ?

I am also facing the same issue when merging unity app with Native app.
