Virtual Camera Gray Screen
All I Keep Getting When I try To Connect Anything To VIRTUAL CAMERA Is A Gray Screen As The ATTACHMENTS BELOW

I figured this out. Simple detail that isn't evident if you haven't used this before. Under tools there's a virtualcam item after install in OBS. There's an auto-start option there that is not checked by default after install.
Make sure you enabled your camera output at Tools>Virtual Camera. I don't know how to do it in SLOBS but in OBS; Tools>Virtual Camera
I have the same problem and I tried to start the camera but somehow it failed to start
Try uninstalling all virtual cameras from registry and reinstall to registry. You can find how to do this on manual installiation section.
Just want to add a few things in what I discovered. 1, this works better with OBS 32bit than 64 bit. If your camera doesn't load in OBS simply bring up the camera settings, deactivate and reactivate.
