Hi I working on animation system for my game, and i have two animations, sword attack and run. It possible to connect this animations so as playing if character is moving and press attack button ? Because if use Animation Blend by Bool attack animation playing but the character does not move legs. I trying mix witch Addtive but this causes strange mesh deformation. I hope for fast help and sorry for my english :).
So on the upper body you want to play the attack anim but the leg should still play the walking anim? When yes, then take a look at this series: 
Thanks completely forgot about it.
I have a problem, i working on animation montage from this Animation Montage in Unreal Engine | Unreal Engine Documentation but i can find last nodes used in this documentation. Where can I find these in UE 4.5 ?
Which ones exactly?
Last nodes on page in link. (Montage Breanching Point)
You will have to create a branching point (Animation Montage in Unreal Engine | Unreal Engine 5.1 Documentation) Then open the animbp - right click - search for the name of your branch point
