I encountered a problem. When Volumetric Fog is enabled and ENB is in use, some hit shaders or spell shaders cause visual bug when everything except player's weapon covers in strong fog effect as on screenshot below.
The problem appears ONLY when in first person mode AND Camera mode is disabled (And ENB is enabled). I cannot play with Camera mode enabled because it is very uncomfortable, I don't want to stop using ENB and I REALLY don't want to disable Volumetric Fog because without it my game won't be as beautiful as it is now.
UPDATE: The problem seems to be in file "meshes\magiceffects\soultrap.nif" (hit effect). I SORT OF SOLVED it by deleting particles branch. Now when I hit someone with soul trap effect, there is no black mist effect on them, but I can deal with it. Maybe someday I will find better solution without sacrificing fancy effects.
