I designed this Viewmodel as a completion of the old Viewmodel Tweak (Update 180) (please, do not confuse with Viewmodel Tweaks). I liked that mod, but it hasn't been updated for 7 years or more, it hasn't been updated since Spring Break 2018 in fact, so I decided to make a pseudo-remake of it, but with the Perfect Viewmodel customization.
Something worth mentioning is that it also has a small extra addition, which is: LMG Ironsights (Perfect Viewmodel edition), which changes the viewmodel of the LMGs when using the scope so that they use their iron sight (similar to PD:TH), but if you want to disable it, open the mod tab during the game and press [Reset] on the [steelsight].
WARNING: This mod (I think) doesn't change the viewmodel of the Little Friend 7.62 or the Airbow, because oh surprise! I don't have the Scarface DLC and because I didn't want to activate the H3H3 DLC. I don't remember if I changed their viewmodels, I think the Little Friend did, anyway it doesn't matter much because those weapons are crap. Cries intensely in Ketchnov
Spoiler!
Have you seen the Tempest-21 viewmodel? (Can you imagine using any other rifle besides the Lion's Roar or the Union 5.56?) Well, I wanted to fix this, and since I had nothing else to do, I set out to customize the viewmodel of (almost) every weapon in the game.
