Use Splines to create Grind Rails that can be easily added to your levels. They adapt to height and have movement logic; the Character just needs to land on top of it. You can change the mesh of the rail and its base, also the materials and how many supports it should have.

The project includes coins and power ups that can be placed around the level. The Bolt power up increases Speed on Rails.
Notes are added inside Blueprints to help you change the logic if needed. A default Third Person Character implements the movement on Rails; you can adjust many parameters. Version: 4.27, 5.1 Home Page: https://www.unrealengine.com/marketplace/en-US/product/spline-grind-rail-builder
