Hi Fehron! Don’t worry mate, you are obviously new to Unreal Engine 4 (UE4) and possibly to animation exporting in general and when you first start out it can be really frustrating. But it was like that for all of us, so don’t worry.
To answer your questions so far:
You cannot edit the character animations in the Unreal 4 Content Examples, such as Shooter Game, Third Person Game, inside UE4. UE4 does not have tools for editing animations. To edit animations you need an Animation software such as Maya, 3DSMax or Blender 3D.
You do not need “Unreal Actor” to export your animations from your animation software or to import it into UE4.
The error message you are getting in UE4 is a general error message from a failed import and could be caused by a 100 different things.
So, in order to help you out a bit more we need to know some more information about your workflow so far to see what’s going wrong.
First off, what 3D modeling / animation software are you using to make your game character and animation? Let me know and we can take it from there.
Okay, so now I’ll describe a workflow very quickly for you to explain how it’s done.
Step 1: Create your game character’s mesh.
Step 2: Create your game characters skeleton. Bind the mesh to the skeleton.
Step 3: Make an animation. Say a simple walk cycle.
Step 4: Export the game character as a .FBX file. (3DSMax, Maya and Blender 3D can all export as FBX as standard.)
Step 5: Import your game character FBX file into UE4. (Includes, Mesh, Skeleton, and Animation).
Step 6: Open the Skeletal Mesh inside Persona and play the animation. Voila!
Obviously I have skipped all the details here, but a lot of the details are specific to the 3D Package you are using to make your character.
Okay, hope that helps!
