Shuttle Loops question

Hello, I’m developing a 3D game where the character is running through shuttle loops. (Think Sonic the Hedgehog) I was wondering if there’s any way in programming the character’s physics to have this effect with the terrain? Please in Blueprints. Thank you.

Perhaps this video can help you, it explains Directional Gravity (in the first part I believe):

Sounds helpful. Thank you for your contribution.
