Hello friend,
So I started lately too donig so, and if I understand correctly what you asked, is the passage through you animations is not smooth enough, is that correct?
In that case I can show you how I did it and why I did it
Ofc you go in your locomotion folder, pick up every animation that you have and bring inside the BS_Walk for example.
Once inside, on the left you set the vertical for the speed and the horizontal for the direction, the grid division depends on how many ways your character can move, I like a deep and realistic animation, so I put 8 and the animations of the case
Then, there is the smoothing time, maybe is the thing you are looking for, basically it prevents to the character to snap like a maniac, more animations you have, less snappy it became.
Once finished here, we can go on the animations of the character, in this case, for me, is ABP_Manny, here we can fix even more the blend time, try to not over do otherwise you will see really weird stuff
Hopes it help!
