But to achieve a slider it's a type of mod that changes the Soldier Animation Tree, so any mod that does the same will be incompatible (none that I'm aware of though).
Aside from that I also made revealing versions of some of the armor parts (it's a WIP, and eventually I may refit more parts at some later point). This mod was initially developed to simply add a slider Customization option, to be able to have soldiers look more or less muscular. \SteamLibrary\steamapps\common\XCOM 2\XComGame\Mods To install the mod just extract it to your game installation mod folder: REMEMBER, THIS MOD IS STILL IN DEVELOPMENT!
