ok the quickest way for you is to use the Epic character rig, how you do this depends on your 3d program, but first you’ll have to export it from UE4.
once you have rigged your character you can import it and just copy the character blueprint from the third person demo, replace the mesh?character and then set your gametype to use your character blueprint
not simple or quick but once you have the character imported it doesn’t take long to get it up and running
