Direct preview doesn't preview in the Focus 3 headset .... only in the Editor window.

[Wazir]

Direct preview doesn't preview in the Focus 3 headset. The preview works but only in the Unity editor window. The headset view says connecting...  Is this an intended behavior? or Am I missing anything here?

Yes, if you are using USB to connect direct preview. 

You will need to use Wi-Fi to connect direct preview if you want to see the image inside headset

@C.T. I'm using Wi-Fi

[C.T.]

did you have the preview image option enable? ?

[Wazir]

@C.T.Yes.

Hi @Dario ,@Alex_HTC, @C.T.

DirectPreview does not work.

Neither in USB nor WiFi mode. The connection just times out. What is your setup to make this work ?

Also, care to explain how to use VBS ? Because it only shows the basic SteamVR layout in the headset, but does nothing when Unity enters Play Mode.

 

Thank you.

Thank you.

I've just checked with wave 4.4 r8 release with Unity 2020.3.32f1, both should send out HMD pose just fine. 
A few places need to check before it can work. 
1. build settings -> need to switch to android 
2. project setting -> XR plug-in management, PC WaveXR also needs to be enabled.
3. if you go with USB, then just start the direct preview APK, and hit play
    if you go with Wi-Fi, please make sure you have entered correct IP of your Focus 3, others for target device. then start the preview server, start device APK.
(it's okay to see connection time out from Focus 3, it will pick up automatically.)

let me know if it works out for you

@C.T.Hello, it doesn't work for me : the image is static in the headset. There are no errors anywhere, the image in the headset just won't move.

[C.T.]

Would you like to zip your project and share with us to check?

[vethetheth]

Sure. When moving the camera in the editor, it does work in the headset. But the headset is not moving on his own, and each eye has a different image of the scene. I tried using those 4 different cameras :

I tried using 2019, 2020 and 2021 version

every parameter has been  tried in wi-fi

WaveXR is ticked on PC and Android platform

directpreview is enabled

Apk has been installed, removed and reinstalled multiple time

It would be really helpful if you help me find the solution.

Thanks in advance
