Character Loses Upward Momentum on High-Speed Ramp Jumps

Hey, how would you go about fixing the issue of a character going at high speeds off of a ramp and basically don’t retain any upward momentum when running/jumping off, they just go straight forward and have no arc.

  1. This second video shows what I’m trying to do. It’s using the Ninja Character Plugin. But I’m trying to build my own system and not use that, I just don’t understand what’s causing this to happen.
