Editor 4.4.2 Crashes on Start With LightPropagationVolumes enabled
As per the topic. If I put r.LightPropagationVolume=1 in the ConsoleVariables.ini I get a crash on Editor startup.
I know that LPVs are experimental works in progress, but I was hoping to see how they worked with a couple of small scenes I want to set up.
I had the same crash behaviour with 4.4.1.
Is this a known issue with this version of the editor or am I doing something wrong?

So I did a little more digging and found the cause on my end:
If I end the OVRService_x64.exe, everything starts up and works fine, including the LPVs.
I initially tried removing nvwgf2umx.dll, which then led to a crash in OVRDisplay64.dll. Then I figured it might have something to do with the OVRService_x64.exe, killed that and lo and behold the editor with LPVs enabled works just fine.
Obviously having the editor crash if I have the OVRService_x64 running isn't ideal, and to my knowledge LPVs were recently fixed (4.3 or so) to work in VR/stereo mode - so I'm not sure what the root cause is.
Hopefully that information helps!
EDIT: The fix may actually be the result of using the power button to turn the Rift off, rather than ending the OVRService_x64.exe. The Rift is currently set to Direct Mode. It definitely has something to do with the Rift being either on or enabled.
There is a known issue with LPV and translucent materials that will instantly crash the editor. We have recently escalated this issue to see if we can at least get a fix in to stop the crash from happening.
To clarify, when LPV is on and if you are starting up the editor with the basic level with the two chairs statue with glass and that table. If you click on the glass translucent material it will crash the editor.
If you're getting different results, please list your steps to clearly reproduce the error and I will test it out to make sure it's not the same issue.
