Vray Physical Camera has stopped working?

Hi Guys,

I’m hoping someone can help me here.
From a new scene:

Create a cube, create a vray light dome, create a camera and switch its attributes so its a Vray Physical Camera (and ‘Treat as Vray Physical Camera’ is ticked) Nothing renders…(Black in VFB)
Untick ‘Treat as Vray Physical Camera’ scene renders fine…

I have a project I’m working on for a client which is having the same issue, so I’d really like to resolve this!

*note - Also…if Treat as Vray Physical Camera IS ticked, and I turn off Exposure Colour Correction, then it renders…BUT then most of the settings in the camera stop working (F-Stop, Shutter speed, iso etc)

Finally, also…DOF doesnt work ..

Can anyone help me here? I have to resolve this ASAP.

Thanks
Matt

RESOLVED! Units was set t oM and not cm which was affecting the light values MASSIVELY.
