NVIDIA GameWorks Integration

At the moment I have a problem with LPV and VXGI. (VXGI build 4.10+VXGI-1.0.0.20520133) In one of my projects I could use both at the same time. But in my current project LPV do not work. I activated it with the “ConsoleVariables.ini”. But when I check it in the output log of my project, the Light Propagation Volume is switched off. I don´t understand . Is there somewhere a resource conflict or something else? Or could be a bug in the current VXGI release? My lights are also set up correctly for LPV. Very strange… I would be very grateful if someone could help me…
