Unity Plugin does not work

When I compile the Client Recognition - Simple application in the Unity and I run it on iPad Air 2 over Xcode I get white screen only. The camera does not work.

I added wikituted native sdk framework to the embedded library, enable bytoce -no, always embed swift standard library - yes and I added camera usage description.


The next problem is that the Unity Editor is not supported...Why? ... It is not effective to deploy every change to the device.


But I am doing something wrong maybe.


Thank you

Hi,


Are there any error log messages printed to the console? Does this happen in the other samples as well, or just in Client Recognition - Simple? Are you building the example project provided, or is this happening after importing the package into your own project?


We are aware that not supporting the editor is a considerable drawback for Unity developers and it is something we want to address. In the mean time, some basic prototyping can still be done in the editor. When pressing play, the recognition triggers are automatically sent, to allow you to inspect your augmentations. Additionally, the recognition events can be triggered manually, since they are just Unity Events, which allows you to simulate some of the aspects of the SDK in the editor.


Best regards,

Hi,

I tested on my own simple project and then I opened the Client Recognition - Simple scene and I tested it too. The same result for both.

This is the log:

Hi,


Are you using Metal for rendering in Unity? If so, please switch to OpenGLES2, as Metal is currently not supported by the SDK.


Best regards,

Alexandru

Hi, 

this was the problem.

Thank you
