Retargeting i have somewhat got down, it helps having pre made ik rigs lol. I think i forgot to set the slide lock pose montage to loop haha that would do it.
This other ALS shooter BP id like to work with is a bit more complex, but seems to define weapon locations based on body slots. Ammo doesnt seem to be split into types on the front end. It has two main variables for the ammo: mag ammo (can change this to ref the ammo in mag var) and bag ammo which seems to correspond with ammo count on player itself. I dont need the weapons to display in slots, as long as I can get them working. I wouldn't know where to start translating any enums either so I may have to be less ambitious here.
