Direct Preview in unity not working - help

Recommended Posts

Could you try ping the ip address again?

Is it still the same?

Usually I will do the following steps,

1. Update IP Address to the Direct Preview Config

2. Install Device apk

3. Start streaming server

4. Start device apk

5. Play Unity Editor

If this fails, stop device apk and streaming server and try again from step3.

NOTE: If it connects successfully, the streaming server will keep printing lots of logs.

One more thing is that when you stop device apk, make sure you did not just exit by pressing the system button on controller button.

It will be better to re-install the device apk to ensure it is completely exited.

so I got some advice from someone else at vive that seemed to help actually start the sever but still getting time out errors, and yes i checked the ip of the device and reinstalled and went through the process you outlined.
The advice i got was to go into Nvidia control panel and make sure the gpu of NVIDIA was selected (in mine it was on auto select, you can see the image attached). I needed to re enable the intel card to get into nvidia control panel. This is the log that i get now, so you see nvidia is in [0] location and it seems to actually start.

after I start device apk should it say connected? Is there some time limit that i need to start unity while it is trying to connect?  I've been trying different things but nothing works 😞 it seems so close now that server is starting.

The server config:.\config\serverSetting.setting is loaded!

BTW I tried to get this to work on another computer and after updating Nvidia drivers there and starting the server i'm still getting a time out error. Can there be something wrong with the headset?

Unity 2018.4 LTS + Wave SDK 3.1.94 as recommended here: 


Could you provide detailed version (2018.4.x) of Unity Editor?

And please update Wave SDK to the latest version, and try again.
