i know that the perk bottle are just weapon files my question is one how do you change the weapon files and two how do i make the weapon file like what animation i need if you can help please comment,

-thanks

All you need to do is export one of the bottles' viewmodels and set it up with a rig. Animate it and import it like you usually would. Name it something different and replace the animation slot within the bottle weapon file.

correct. im pretty sure its the pullout anim
