[Unity Tutorial] Direct Preview (video update)

[dario]

What's Direct Preview : 
In the development process, building APKs repeatedly in Unity is time-consuming. Direct Preview lets developers skip the build process by letting developers preview in both the Unity Editor and their headset simultaneously.

Hey Dario, I've been trying to get the DirectPreview up and running with the VIVE Focus 3. when I enter play mode within unity I can see in the editor's game preview it's tracking the HMD's position, as well as the controller's position just fine. but when I put on the HMD I can't see the preview withing the device itself, it's only showing me the VIVE loading spinner. I was wondering if you know of any to solve this issue.

Hi @Kaj,

Thanks for feedback. 

May we know your Wave SDK version? 

Since D.P supports both USB and WiFi connection, a faster way to quick clarify to switch another way for a trial.

If still no lucky, please grab the logs for us to further clarify, thanks.

I tried both USB an Wi-Fi and neither seem to display anything.
I'll send you the logs from yesterday's try-out. i tried it with unity's VR Template, and some of the example projects that's listed with WAVE SDK, Essence, native. in the package manager.

I'm using Wave SDK version 5.3.2-r.4

I checked the logs and found this.

[2023-09-04 12:04:19.650 +1 0x2148 INFO RRModReport] Server Variable (BOOL) changed IsHMDReadyToReceiveVideo = false

[2023-09-04 12:04:19.651 +1 0x3E74 INFO RRModDriverAgentWave] BOOL Server Variable changed IsHMDReadyToReceiveVideo = false

it's probably only part of the story, so here are the rest of the logs.
