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

[julie.helbecque]

Hi! I have issues using Direct Preview as well. When I want to use it, the pose of the headset is indeed correct in the unity editor, but all I can see in the headset is "Connecting...". I have a project using URP and the target device is a Focus 3. I am sure that WaveXR is ticked on the android and PC plateform, both devices are on the same network. The streaming server doesn't indicate any error. I use the wifi connect type, the headset ip address, I have indeed ticked "Enable preview image", the update frequency is 15 FPS, the render target device is "others", the preview image ratio is 0.4 and i didn't ticked "regularly save images". Could you tell me if you have any idea what to try to solve my problem please ?

Thank you for your answers

Could you tell me if you have any idea what to try to solve my problem please ? Moreover, during my tests one of the pc I worked with raised an error telling me that I had to update my nvidia drivers, which were up to date. This pc had the graphic card NVIDIA GeForce RTX 3070 Ti Laptop GPU.

Thank you for your answers

I don't think it works with urp

Lots of thing don't work with the preview, even the preview itself.

I just posted in this URP-related thread asking about the same thing. Can see pose updates in the Editor during play, but HMD shows "Connecting...". The only thing left that I can guess is that this is some URP incompatibility preventing the camera to be streamed to the HMD.

Hi @julie.helbecque, @vethetheth, @Austin Sullivan Unity,

Sorry for the late response.

Currently we're working on Direct Preview refactoring to improve connecting stability, user flow and add new feature like hand tracking support etc. and plan to have an update version with next SDK release (in March timeframe). 

URP support is on our plan, but it also requires more efforts and investigations to make the whole paths work. Will keep posted if the schedule is confirmed.

Thanks.

Hello Tony, is the direct preview update still on track for march ? This feature will be decisive to know if we leave htc for other headsets.

Hello,

It still doesn't work with URP right?
