XR Elite PassThrough Problem

[Ring]

I want to enable passthrough mode on XR Elite through Unity, but no matter what I try, I only see a black screen.

I'm pretty sure that I have set the camera's background solid color to black (0,0,0,0).

And here are my code.

Is there any detail that I might have missed? I'm really going crazy.

I would be grateful if someone could provide me with some help.

By the way, I'm using Unity 2020.3.40 URP

Hi @Ring,

Have you tried referencing this link for Passthrough and seeing if it helps resolve your issue?

Hi @Ring,

For myself, I will do the followings,

private Color? recOriginalColor = null;

//In your show passthrough underlay function, add below code before calling Interop API
Camera.main.clearFlags = CameraClearFlags.SolidColor;

if (recOriginalColor == null)
    recOriginalColor = Camera.main.backgroundColor;

Camera.main.backgroundColor = Color.white * 0;

//In your hide passthrough underlay function, add below code before calling Interop API
Camera.main.clearFlags = CameraClearFlags.Skybox;

if (recOriginalColor.HasValue)
    Camera.main.backgroundColor = recOriginalColor.Value;
else
    Camera.main.backgroundColor = new Color(49f / 255f, 77f / 255f, 121f / 255f, 5f / 255f);

 

Let me know if you still have issues.

Hi, @chengnay,

Thank you for your code. It works for passthrough, but in my case, the virtual object disappears.

Besides that, I tried creating a new Unity project and copying the scene over to the new project, and everything worked fine. So it seems that there was something wrong with the original project that caused passthrough to not work properly.

@Ring
Based on your description, I suspect that some example code that calls PassthroughOverlay is running in your previous scene. Look for example monobehaviours (like our passthrough example code) that may be calling that by default.
