Black Mesa Models in Gmod

I imported some of the BM models into Gmod, All of the Human models. I dragged all of the textures from the humans folder also so every file the models need. Yet two the models are glitched up. Only the guard and the assassin are messed up though, the rest are fine. My question is, What am I missing?

The Guards are missing what looks like reflection textures

The assassin has no bodygroups and it’s model is glitched up.
