The files this is based off of are from shared GCFs. Anyway, on to the actual description.
It's Fixed. Go ahead and download.
I had been trying to get this to work for a long time. First thing I tried was changing attachments. Nothing. Second was editing the animations file. SCREWED EVERYTHING UP. Finally, I noticed that the animation events used to shoot in HL2 and HL1 were different. I just decompiled the model and animation files, added the required animations to the model file, changed the animation events, and recompiled. I was freaking happy.
Custom skins made for the HL2 Vortigaunt will work with this EXCLUDING those with custom models. They will fail if they use a custom model.
Also, this will NOT work with illegal versions of the game, and I will not help you make it work.
NECK GLITCH AHEAD
Yeah, the infamous "detached neck" glitch happens here. I don't even know, there's not much I can say about it, just be aware, the neck is all detached and crap.
EDIT: I'm happy, as this is back. I'd like to thank, and apologize publicly to Xero. After he trashed this, I said some rather mean things spoken out of anger.
