Animationing sequence (walking) on NPC with existing animations (Mixamo or Blender)

Hello everyone,

complete begginer here.

I have been trying to make my custom NPC walking path on UE5. I have successfully done it following some Youtube tutorial using the BP_Character.

However, the Mixamo and Blender imported animations have different files and i cannot wrap my head around how to make them work.

I have tried using the same blueprint sequence as i did on the successful character, yet the animation is still performed in one place.

Do i have to combine the animations to make a BP and start from there ?
or
Can i just use imported animations and i have to do the functions internally

Hope i was clear

Thank you in advance
