Animation Montage Specific Bone Select?

Hello there.

I have been trying UE4 again in hopes of accomplishing something with less unrealistic goals. I’ve made a simple Mushroom Character and got him running around an area as a character does. My problem lies with my attack animation. I’ve set up a montage using the UE4 Tutorials and everything works fine. Except when my character attacks, its like the idle or running animation continues on the upper body as im attacking and it doesnt quite blend correctly. I cant really show you because I dont know if i can upload a gif.
The mushrooms head jump back into the way it would be if he was running or idle without the attack.

There is a point during the idle or run state that his head jults into position as if to match the idle or run. Is there something I need to do to make transitioning from attack to idle or run smoother. I’m using the animation montage in order to be able to attack whilst only effecting the upper body, My main query is whether i can set the bones of the upper body to ignore the head; maybe then it wouldn’t mess the head movement around. It’s not easy to explain so I hope I managed to make a little sense. If you need more information, ask away. Any help would go a long way. Thanks

So I figured out my problem. For some reason the only thing I had to do was change the Blend Out Trigger Time from -1 to 1 and it exited the hitting animation smoothly. Here’s a screen-shot of where it is in the animation montage -

maybe someone can enlighten me on its purpose if i’m not understanding it’s true use. Otherwise, fixed.
