How to do glide a character

what I can suggest is if U want a good result U can import ur character in any modelling software(Blender,Maya loads of stuff to choose from) then create an animation and import it inside UE4 . However I may warn U sometimes it happens that the animation is broken as soon as U import the character inside UE4 .Do not panic check the bone orientations . I hope U are familiar with skeletal mesh terms by now .If no again do not panic read the docs. to clarify

here is a video of how to animate using blender and how to import and export animations
Tutorial: Mixamo and Blender :

Blender to UE4
Blender animation creation

or if U are facing problems with character bone orientation and all other stuffs
then follow this

also U can attach the bone structure of one model to another . So, the bone orientation size and all other stuffs are properly maintained for the character and just need to import and attach the created animation to Ur character.
