BlueprintUE.com is a tool for sharing, rendering and rating blueprints for Unreal Engine 4. UE4 is a game engine which use visual scripting called blueprint.

In this Livestream Tutorial we'll show how to use both Spline and Spline Mesh Components to construct an easy-to-use racetrack generator tool in UE4. Viewers will learn about custom structs, functions with local variables, using for loops, and much more!
