Offscreen rendering don't seem to work under Linux and Vulkan

I’m trying to get UE4 to work in a compute cluster with DGX2 servers. In practice this means that I have to get offscreen rendering under Vulkan to work inside a docker container. As a first step I’ve tried to get offscreen rendering to work on my workstation (no docker). My machine has Ubuntu 18.04 with NVIDIA 440.44 drivers and two TITAN V GPUs.

I created a simple sequencer inside the StarterContent project that comes with UE4 and then tried to render a movie using the following command:

Engine/Binaries/Linux/UE4Editor /home/efagerholm/ue4/UnrealEngine/Samples/StarterContent/StarterContent.uproject -game -MovieSceneCaptureType="/Script/MovieSceneCapture.AutomatedLevelSequenceCapture" -LevelSequence="/Game/Sequence" -MovieFolder="/home/efagerholm/ue4/output/" -NoLoadingScreen -MovieFormat=JPG -MovieQuality=100 -ResX=1920 -ResY=1080 -vulkan

This works just fine. Has offscreen rendering on Linux with Vulkan been tested and has anyone managed to get it working? Adding the -RenderOffscreen flag I get instead a segfault and the following log output:



efagerholm@efagerholm:~/ue4/UnrealEngine$ Engine/Binaries/Linux/UE4Editor /home/efagerholm/ue4/UnrealEngine/Samples/StarterContent/StarterContent.uproject -game -MovieSceneCaptureType="/Script/MovieSceneCapture.AutomatedLevelSequenceCapture" -LevelSequence="/Game/Sequence" -MovieFolder="/home/efagerholm/ue4/output/" -NoLoadingScreen -MovieFormat=JPG -MovieQuality=100 -ResX=1920 -ResY=1080 -vulkan -RenderOffscreen
