Rootmotion Jump

Hi everyone !
Hi completed a rootmotion controller with 3 states (idle walk run) and with 180° turn based on the Kubold movement animset. With that, I want to add a jump animation but when I add it, the character don’t move on the Z axis and he slow down at the end of the animation … How can I fix it ?
Thanks for reading me !

I managed to add the jump Z velocity with the “jump” function of unreal engine (that was really simple … :p) but the jump isn’t that good : the distance is very short, and I need to cut the animation (time remaining ratio) because the character lose all his speed at the end of the animation … If anyone can help me or know an other way to do root motion jump …
thanks for reading
