Is there a way to use a hand held virtual camera in unreal while in game or simulating?
with the vcam actor and app it doesn’t seem to be possible; or ist there any hack that im not aware of? will become possible in future releases like 5.2?
If there any different way to use a gyroscope based device in-game or while simulating as a virtual camera?
In 5.3 I was able to control a VCam Actor while in Play, with functional UI and everything. It’s also important to uncheck Enable before unloading the VCam
Unfortunately I’m having a “Fatal Error!” if I try to Enable the VCam Actor in a packaged build.
Has anyone had success with that?
Hi @data_morphana , I am trying to do the same with my game. it would be great having the vcam as controller in game. I haven’t found a solution yet. I believe that the behaviour should be the same as using the VR. Has anybody solved this ?
Can you post your UE and VCam app logs?
Hi, unfortunately the crash happens before I can even try to connect to the VCam, so I don’t have logs as far as I know. This is the only error message.
This is how it happens:
I created a simple Button which runs this code when pressed:
Only once, while packaging, I had this crash, but I tried again immediately after and it was successful.
Could the problem be the Pixel Streaming?
Can you go into the project and /Saved/Crashes/ and get the log in there?
But the repro would be to Enable the VCam, go into Simulate, run that BP, and then crash?
Empty_ambient.log (170.3 KB)
I see, it seems like this log has quite a few clues!
It’s still weird that in the Editor I can’t get it to crash, even if I enable it before simulating.
Here are what I feel are the more salient parts:

I also see a bunch of these errors:

Ok this looks to be a bug. It’s attempting to load a lot of editor-only stuff. I’ll JIRA this.
Thanks! 
Looking forward to a future update!
