I have searched for this very thing Nebula, but I have not found anything other than the socket transform, socket rotation, socket rotation nodes. I have not yet figured out how to grab the socket transform at a specific point in time. I noticed in Anthem there is a disconnect between the launch of the grenade and the animation. It almost appears the solution in Anthem was to speed up the animation. In Fortnite I think they do two things. They spawn the grenade in the hand, but do the projectile prediction from the front of the head. They then spawn the grenade from the front of the face to launch and destroy the one in the hand. Def need some help here. I have not yet set on a solution.
