VGAO works really great but I am having a problem. With console command:r .VXGI.AmbientOcclusionMode 1 ,I can isolate AO from entire VXGI and reduce the performance impact. The AO pass looks great without any flickering like in SSAO. However, when I turn on VXGI, I only see AO overwrites the scene without any materials. is my problem and I cannot figure out why and how to fix it.
