NVIDIA GameWorks Integration

I have a problem with the substance plugin and vxgi (since 4.13)
I have been able to compile it, when i launch UE4 i do get the plugin in the plugin menu and i’m able to use it and import substance material…but none of the parameters are working anymore.

I feel like i’am the only one ever disapointed about problem and i really wonder why…because Substance+VXGI both at the same time would be quite a dream to me!
