I have my character in idle, when I try to use this animation the character suffers a movement but immediately returns to his current position. How can I keep the new position?
Does your character have a capsule component? Where is it during the animation?
My guess is that the animation has root motion causing it to leave the location of the capsule collision. I believe this is the answer you’re looking for: Capsule component doesn't move with Animation - Character & Animation - Unreal Engine Forums
If that’s not what you wanted, let me know. 
Thank you very much!
