messed up models, and particles, i do not believe this is a bug

okay so installed a few mods(to black mesa), but the last one mess up the files, so i when and moved out the newer one with one that shouldn’t have issues, but it did, so i made a new set of files and put them in, still failed,
the issues are

  1. the eye texture is missing
  2. particle system is goofy and i can tell isn’t working right
  3. all models are the bloody versions
    here is a screensshot i took when noclipping around in the frist chapter

so is there any way to fix this

my system: win 8(it was formally win 7, but then i upgraded because i don’t like win 7 i had a laptop burn out on win 7, so i hate it, and that is not the issue i have been playing it before no issue before i installed mods(to black mesa, so don’t say go back to 7, as i hate it -_-)
and other hl2 mods installed: missing information, and fortress forever
half life 2 and it’s episodes work okay without issue, it’s just black mesa
