Add flipbook to hud, or a placement for a 2.5D Sprite on player BP that doesnt shift

Hello- im making a 2.5D shooter and was wondering how you would go about adding a flipbook into the HUD. If not, is there a way to place the sprite on the player camera in such a way that if the FOV were to change, it wouldn’t be massively displaced? I want to be able to adjust the FOV and not have my hand/gun floating in the air as a result.
