Character blueprint with Metahuman - Floating hands. Please help

Hi. I did but I figured it out. But I still am unsure of something. Where I’m at with my FPS metahuman character is far from the default so I’m pretty unsure of which tutorial I should follow to add I guess mixamo animations to my character.

Also, if I add a walking and holding Pistol animation, can I edit that animation to turn it into a walking + Pistol aim animation? Instead of just holding the Pistol. Plus there’s side strafing and backwards walking animations and jump ones, and I need to have all those animations for each weapon. Do I need a separate animation for every single situation? Or can I duplicate them and edit them to be what I need somehow and put them all together I guess in a blendspace?

Animations are my biggest weakness so I’m just confused about where to go from here.

Hope you’re well.
