Go to and install MelonLoader onto the Unity game you want to mod.I implemented it into a mod and did lots of testing. This makes the mod much simpler and more universal. I would like to thank for programming this version of the script which directly references openvr_api.dll, eliminating the need for referencing Valve.VR.
This is Version 2.0.1 of the MelonLoader Unity Universal Culling Fix Mod.
