[BUG] No UE 5.5.3 games enter VR.

Open mark-mon opened this issue 9 months ago • 6 comments

Describe the bug

No UE 5.5.3 games will enter VR. They inject but stay on the 2d screen and never kick into VR. If using streamvr, you are at the waiting screen forever.

Tested with:

  • Biohazard Siberia (the actual game, the demo is not 5.5.3 and does enter VR)

  • Asgard's Edda (not working) is probably easiest to reproduce as it has a free demo: https://store.steampowered.com/app/3064320/Asgards_Edda_Mechanical_Threat/

  • Also bloodkill goreblast (not working) is 5.5.3 with a free demo: https://store.steampowered.com/app/3420690/BLOODKILL_Goreblast_Overkill/

  • Also bonk it (not working) 5.5.3 with free demo: https://store.steampowered.com/app/3204780/Bonk_It/

  • Brutalistika (notworking) 5.5.3 with free demo: https://store.steampowered.com/app/3372000/BRUTALISTIKA/

  • Blackshard (Demo at least uses 5.5.3) https://store.steampowered.com/app/3223390/BLACKSHARD/

  • House of lost souls

Tested UEVR nightly 1040, 1.05 and 1.04.

Multiple users reported so is not system specific.

I can confirm this issue is something inherent to this engine version as its present in a completely blank first person project. Extreme compatibility does work so I guess your UE5 render target scan function will need to be redone again. I would have liked to get more info but I didnt have symbols downloaded for this engine version and debugging attempts just caused crashes. will try again with symbols but I suspect you may have some ideas already

UE 5.5 games are not supported. UEVR only supports up to 5.4
