After the desync update, new thirdperson animations were added to the game. Unfortunately, someone at Overkill forgot about cbt_crh_shoot.animation for dual pistols, which still uses the old pre-desync update animation. It's not too noticable in the heat of a match, but I noticed it, and it bothered me. The character tilts left and right when firing which is due to the different positioning of the animation's lower body. I went ahead and made a new animation to fix this.
Notice
This mod is incompatible with anything that edits cbt_crh_shoot.animation for dual pistols, though as far as I'm aware there are no mods that also do this.
It's probably not a good idea to use this mod on a version of the game prior to the desync update.
Trivia
Spoiler!
Not much to say other than ask a question: how the hell do I notice these things? I feel like I could be a good debugger with how much random, insignificant stuff I notice. Another issue with dual pistols being, Chavez in Panic Room has dual glocks. Dual pistols use the pistol hurt animations, and since those weren't set up for dual pistols, the leftmost pistol twists at an odd angle when the animation plays. That's just one issue regarding this game's animations, among other things... Don't get me started on the "bullpup" animations.
