The Rail Cart System 5.1+ is designed as a basic and easy-to-implement and expand rail system for your projects. All the hard work is largely handled for you—just create your spline track, add the cart, and adjust a few properties to customize it to your needs. The system includes multiple rail track sections and a function to randomize the spline mesh components, helping to avoid repetitive track parts and adding dynamic variation during world building.
Update: The asset is now fully replicated, including interaction systems. A new checkbox has been added to splines to hide the track mesh, addressing UE5’s performance impact when generating long splines. You can hide the track, set up the spline layout, and then enable the track mesh to check if it meets your requirements. Additional performance improvements have also been implemented.
