Launch Character Launch Veolcity Confusion

So I can test the Launch Character Function in the blue print. If I manually set the Z in the velocity vector I can see myself jump that amount.

I’m trying to make my jump scale based on how high one looks with their mouse. So I Get World Rotation plug that value into the Get Up Vector then plug that value into a vector x vector (where I have some constant vector * Get Up Vector) and then plug the product of the two back into the Launch Character’s Velocity.

I print out the value of the Get Up Vector and I can see it change. I can also see the Z for the vector of Launch Veloctiy change, however in game testing of the launch shows that it does not. The Launch Velocity seemingly stays constant on execution, despite the vector clearly changing in print log. If I had the constant z at 1000, print log will show that the z is lets say 400 (which is getting sent to the Launch Character Velocity vector) but I’ll still jump 1000. Doesn’t care about my Look Up Vector it seems.

I have no idea why.
