HTC Vive passthrough camera AR/VR development

Hi @Rectus_SA thank you for pointing me out in the right direction. I follow their approach to get a mixed reality background, but have run into the issue that when I toggle that function the app freezes.

Of course I took into account and not used those required Varjo plugin nodes, and just bypassed it with some variables I control. The problem is whenever I run the command to blen the environment, the application within the headset enters in the “waiting…” status, which is funny because in the Preview window it is still running (but no passthrough or camera feed being shown of course)

I runned the steamvr webconsole in an attempt to get some more information and debug what could be going on, but only noticed the next statements

But in essence the only thing I am doing is the similar approach of “xr.OpenXREnvironmentBlendMode 3” but there is no mention of that in the log messages

But then the output log from UE actually shed some light into the topic, I am trying these with both Valve Index and HTC Vive Pro 1/2. But no sucess with either.

Any additional resource I should check out in an attempt to get that “mixed reality window” running through these devices?
Thanks for your time and assistance!
