Weird... Texture Glitches

[Yoshiboo]

Alright, this has never happened to me previously, but... basically, some of the cosmetics in the model viewer have a weird red and black checkered "missing texture" texture (instead of the usual purple and black), and below it, there's a "tf/workshop" model of the same thing (doesn't exist for some models), but its textures are all black, unlike vanilla models. I have a feeling it's from some of the cosmetic fixes I downloaded, though I'm not thoroughly sure. I've tried deleting one of the fixes that I had, but still laid unaffected (yes, I rescanned, and restarted SFM).

Examples here with the "Doc's Holiday" model, or "medic_hawaiian_shirt"

open the VMT for the misc Items, search it for anything that is a texture (like basetexture, bumpmap, detail or phongomethingmask textures, etc. then check to make sure that those VTFs exist in the paths specifed. (Black and purple checkerboard mean the VMT or the $basetexture VTF are missing. Red and black usually means that one of the other VTFs being called by the VMT are missing.)

Nice to see you, sorry for such a late response. I found the location of both the vtf and vmt files, and saw what you meant. Some of the files did have missing vtf texture files in the materials folder. I only have two questions now: is there something that I can do to regain the vtf files, and is there a way to prevent this from happening again?
