Wow, I’m so proud!
Yes you would need to make a separate animation for grabbing the weapon and putting it in the holster, that animation could be fired when the player presses the “F” key for example. Once the weapon is actually in the characters hand using sockets, the weapon will be attached to the characters hand wherever he points. You can then tie the controller rotation to camera so your player is pointing in the right direction to shoot.
Here are some questions to ask yourself, will your character always have a weapon in his hand and break the aim offset animation to switch weapons with the unholstering animation. Or would you like your character walking around hands to the side sees weapon (animation) picks up weapon then initiate the aim offset blendspace once weapon is in hand.
Easy way, have no animation for switching weapons, so when the character presses the “F” key for example, within blueprint the old weapon disappears completely or you switch to another weapon. Kinda like how Grand Theft Auto use to do it. I don’t think they had an animation for putting the gun away or pulling it out, back in the day. I don’t think the weapon could be seen on the character either. I may be mistaken.
Your doing great, keep it up!
