Oculus Launcher seems to cause ue editor to crash in vr mode

Oculus Launcher (even opened in background) causes ue editor to crash in vr mode.

If I reboot and never launch oculus launcher, ue editor in vr mode seems fine :frowning:

Anyone else having this issue?

Latest version of nvidia drivers, ue 4.18, oculus 1.2

I seem to be having this problem too, but I also can’t see how to stop the Oculus launcher from autostarting when I launch VR.

Seems to have been fixed in 4.18.1

At first, 4.18.1 didn’t fix it. But, after allowing beta updates for the Oculus software (it calls it “test channel” in the options), VR preview now seems to be working.

VR editing mode still crashes after a few seconds, but I don’t intend to work with it, so that’s fine.

yeah mine started crashing again… worked for a while… going to try beta

so updating to oculus beta (opting in to Public Test Channel) (and latest nvidia drivers and 4.18.1) seems to be working… at least for now.

:slight_smile:

Correction - the crashing started again :frowning:

Going to try the latest oculus integration via source

Is the crashing related in any way to DirectX11? Did you have a look at the Crash Log?

Not sure - seems to be related to some editor viewport stuff?

I am downloading the oculus integration source and gonna try a debug build - but that is gonna take a while.

Here is stack trace:

I am getting plenty of crashes/blue screens since the Nvidia drivers 388.xx. I am rolling back to 387.92 as I type this.
