Sliding Animation

Animation I used in the Parkour Slide video. 

To correctly import this, first drag the animation into your content drawer and select the base UE4 skeleton. Don't use the new manny skeleton for import. Use the old Mannequin UE4 skeleton that you should have in your project under characters. Then once the animation is imported you can easily retarget it to UE5 skeleton.
