Agreed on ABS stripes
Agreed on texture, anyway as mentionned earlier they've used the same likely.. everywhere, so they spare game's ressource
Concerning the pouches I believe far more in a 3d model collision issue (objets going through another one, "ghost/noclip" mode) than an actual attachment of these on the tactical vest strap
They are actually, just like the holster, just like the MP40 pouches, simply " stuck " or "dropped" over the other elements with no actual attachment system (no loops either, it all holds with magic)
So we have to choose what does make sense. It's not an ultra detailed 3d model so we also have to adapt it to Real Life by assuming logic stuff. It's not because we don't see loops there should be none, the pouches are not held on belts with glue or rivets, the logic here would clearly be loops.. Simple, convenient, logic, I mean, let's not over-amplify difficulities on an already quite complex uniform
IMO it doesn't make sense to attach pouches on the tactical vest strap, as IRL, they will likely hang from it and won't fit closely onto the body as they look in ref pics, which won't give a clean render. It will also obstruct the quick release buckle of the tactical vest strap
