In your Fallout: New Vegas folder, open your enblocal.ini, and make the following changes Not strictly necessary, but I think an obvious stumbling block that people have with ENB’s is that they haven’t got the settings right for their system And (anecdontally) go to Data/Shaders, and replace shaderpackage013.sdp with a copy of shaderpackage017.sdp (make a backup first!).Use FiftyTifty's fix for a far more drastic solution, or both (load mine last) Changes hair mesh flags so that ambient occlusion doesn't shade areas which should be transparent.
