I cannot play VR multiplayer client side within editor.

Hi,

I don’t know if I’m missing something or this feature was turned off but I cannot seem to get VR to work client side when doing a VR preview with two players and playing as the client. If I play as the listen server it works just fine, the VR preview comes up the client window comes up and logs in. When I play as the client the server window launches, the client window launches and is the proper side. It even picks up the rotation of the headset but nothing displays on my headset. This worked just fine in UE 4.11, I skipped 4.12 and went right to the current version (4.13.0). I even started a fresh project just to see if it was something I had turned off, but it just won’t work. I read lots online about using execute console commands but they did nothing, I also read one answers post about commenting out some code from a GIT pull. Nothing helped. It would be really nice to be able to test our game from the clients perspective within the engine and not having to constantly build.

Steps to reproduce.

  1. Start a project (any project will do)
  2. Editor Preferences > Play > Multiplayer Options >
  3. Set the number of players to 2
  4. Set your “Editor Multiplayer Mode” to be “Play as Client”
  5. Play the game

In 4.11 the client version works in VR. In 4.13 it does not.

Thanks
Russ

i’m having a similar, but different issue. have you figured anything out?

Short of going back to 4.11 I have not figured anything out. I would say both issues are related because they are both 4.13, I’m running a rift but both are headset related. I am currently waiting on a response. I would honestly be surprised if we were the only two. If nothing else I should know more by next week. I have a regular job working in VR and we are going from 4.11 to 4.13.1 next week, so if they can’t fix it… well I dunno then.

this guy had a slightly different problem but he says he just ditched the camera manager altogether and it worked. i have not tried this yet

no dice.

i just verified that 4.11 works. 4.12 does not

Yeah, i find it hard to believe that we are the first guys to have this problem. My post has been o here for a few weeks without a reply from someone from Epic. Maybe now that the issue has doubled interested (from one to two :-p ) we can get a response. I’ll let you know if anything happens where I work next week, I fully expect us to have the same problem.

i think i’m onto something. in 4.13 i’m getting

LogHMD:Warning: Standalone game VR not supported, please use VR Preview.

but this does not occur in 4.11. it looks like this was an issue in 4.10 though, so i’m not sure why 4.11 would be okay. i suspect that since multiplayer forces standalone it’s causing the HMD to not get connected. this guy says he was able to hack it to work, but i’ve not tried it yet

have you submitted a proper issue? the closest one i was able to find was this but apparently it’s not slated to be fixed until 4.15

Do you happen to know if I’ll have any significant problems with performance or vr support if i migrate from 4.13 to 4.11?

Hey SlimeQ,
I saw that one about removing the line from the playlevel.cpp. I couldn’t get it to work but I’m also not a programmer so I really wasn’t sure what I was doing. There seem to be plenty of people asking but nothing coming out of Epic about it.
