WAVE XR passthrough sample issue in Unity

[AdamCheng]

Hello everyone,

Recently I've been testing the passthrough function of VR Headset. However, I had problems running PassThrough or PassThroughOverlay in the sample.
The package manager is already installed with VIVE OpenXR plugin & VIVE Wave XR Plugin.
However, there is a DllNotFoundException problem when running. 
I searched my computer and found wave_api.dll I copied it to Assets\Plugins , but unfortunately the problem is still not solved.

Does anyone know what this problem is or how to solve it? 

My VR Headset is HTC VIVE PRO EYE
Unity : 2021.3.2f1

If you are developing for vive pro eye or any of the PCVR content, you do no need any of the WaveSDK. 
Wave SDK is specifically for VIVE AIO devices including Focus 3 / Vive Flow

@C.T.Thank you for your reply.
Do you have any good suggestions?
Because I have tested SRWork SDK, and it seems to have problems in Unity 2020, 2021.

That's why I'm testing with Wave SDK.

@AdamCheng Did you ever try Vive_SRWorks_Demo.exe in SRWorks_v0.9.7.1_Unity_Prebuild_Samples?

If yes, could you paste your result? Thanks!

I am trying to clarify and resolve your problem.

[AdamCheng]

@chengnayYes, I have tested the SRWork sample.

When I import Vive-SRWorks-Unity-Plugin.unitypackage, I get a ModelImporter error.  (In Unity 2020 & 2021) 

 

I tried to fix these errors.  

But there is still a new problem, so I added csc.rsp to the project folder \ Assets with the content -unsafe file. 

 

When I play in Unity, only Unity has a camera image but there is a problem. VR Headset is no camera image.

Final result I record a video and upload to my Youtube .

Did the SRWorks sample work for you? Did you see camera image inside the VR headset?

[chengnay]

@AdamCheng If you would like to use SRWorks SDK, it ONLY supports Unity 2019 which I just tested OK.

There is another option for you if you would like to develop using Unity 2020, 2021 which is OpenXR version.

Please let me know if you have questions or issues, thanks!

@chengnay

I have testd SRWork sample with Unity 2019 before. It works properly in Unity 2019. 

But, VR Headset is no camera image in Unity 2020 or 2021.

Thank you for the information, I will try it.

@chengnayVIVE FOCUS 3 using wave SDK work with Unity2021?

@AdamCheng,

Which Unity 2021 version are you referring to?

For me, I did use 2021.3.3f1 and it is ok.

Let me know if you have issues. Thanks!
