Help with animations needed here

Guys, I’m new to Unreal Engine and I wanted to ask something. I’m working on a project, where the main character sooner or later will habe to draw a weapon. The question is, how can I make the character pass from an idle state to a weapons drawed state when the player changes map?

are you using a anim bp? if you are then you could have a bool variable in the character named something like weapon drawn, then in the anim bp you have a transition based on that variable. so if weapon drawn true then the anim bp will transition to using a branch for weapons. otherwise you could use anim blending, or if its something that will only change between levels you could use a separate anim bp.
