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 canā€™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 didnā€™t fix it. But, after allowing beta updates for the Oculus software (it calls it ā€œtest channelā€ in the options), VR preview now seems to be working.

VR editing mode still crashes after a few seconds, but I donā€™t intend to work with it, so thatā€™s fine.

yeah mine started crashing againā€¦ worked for a whileā€¦ 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 workingā€¦ 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.
