Here is the solution but I’ll explain what’s going on for people doing something similar in the future. You basically want to trace between the actor and what they’re aiming at, then find the distance of the vectors, divide it by 2, and multiply it by the actors forward vector, and add some Z for the jump effect.
I didn’t end up using suggest projectile velocity and would still like some insight as to how it works, but this is a nice solution which achieves the same thing.
