Hi! We have two apps - one runs on ML2, and another on Windows. We need to stream what user #1 sees in ML2 app (NOT a video from the external cameras, but a texture from the app) to the user #2 on Windows.
We use this code to get a texture from the MagicLeap camera, specifically from our app, to stream what a user in ML2 app sees to another app user on Windows. However, when getting the texture, a critical error occurs. Below is the text of the critical error.
**Unity Editor version** : 2023.3.27f1
**ML2 OS version** : 2023.3.27
**Unity SDK version** : 2.5.0
**Host OS** : (Windows/MacOS) windows 11 x64

Do you mind providing more information about your implementation? Based on the logs the error is coming from your implementation of streaming the viewport from the Magic Leap. Specifically `Byn.Unity.Examples.VirtualCamera.Update()`
Have you considered getting the image of the Virtual Content using the Magic Leap Camera API? The Main Camera Stream can be configured to stream either Mixed Reality or Virtual only content. These will display what the virtual content from the user's point of view.
