UE4 Not Recognizing Vive

Hi there,

I’ve been having some difficulty getting UE4 to recognize the Vive and allow for the VR preview option to be used. Yesterday, I was able to get it working for a bit after using the “HMD Enable” command, but then later it went back to not working randomly. The VR preview button is greyed out and none of the VR console commands are recognized. Otherwise, the Vive is functioning properly within Steam and its applications. I have checked and the SteamVR plugin is enabled within my project, so that shouldn’t be the issue. I’m using UE4 version 4.9.1. Does anyone have any insight as to what might be going wrong?

Thanks in advance!

We are having the same problem! and its crazy it worked and now it isn’t. Did you happen to find out a fix.
