R-Tune is a custom vehicle physics solution tailor made for Unreal Engine 5 written C++ from scratch for the best possible performance. Using the custom R-Tune blueprint components, you can easily create vehicles in less than 2 minutes! No more working with tricky skeletal meshes that require pre-rigging and initial mesh setup - a simple static mesh for the body and wheels is all that is needed. Animation is fully procedural with overrides exposed for precise control. It is fully replicated with smooth client side movement and anti cheat features.

This system is designed to be modular and expandable. The core parameters are exposed for override (torque, RPM, wheel angular velocity, etc) so that vehicles can be modified at the core in order to produce the behavior required for you specific project. All done in a non-destructive manner. It is also is FRAME RATE INDEPENDENT. These vehicles will behave consistently, smoothly and predictably at any frame rate, regardless of how low or high it is.

This is designed to be both easy to use for beginners, as well as provide advanced and robust functionality for advanced game requirements. The physics model supports a wide range of vehicle types, from cars to trucks, buses, tanks and any vehicle with N-wheels. Virtually any type of vehicle or vehicle behavior can be made!

Scalability

Other vehicle systems may offer an 'easy setup'. It seems like the perfect cost effective solution. But very quickly the cracks begin to show. You want to create a unique vehicle ability, but the system is a "black box" that you can't modify. Parameters are exposed - but the actual core is not. The cheaper choice at the start has become a dead end that has slowed your project to a halt. Choosing the right foundation is the most important decision you'll make for your project.

An Open, Extendable Architecture

An asset becomes a trap when you can't change its fundamental behavior. R-Tune is built to be expanded. You will never hit a hard feature wall. Core parameters are exposed for you to override and control in Blueprints. You can easily add custom logic for unique abilities like boosting, tap-to-drift, or even change driving mechanics mid drive.

Proven to Handle Any Vehicle You Can Imagine

A system designed only for cars will struggle when you decide to add something different. R-Tune's architecture has been battle-tested across a huge variety of vehicle types. Your creativity is not limited. The same core system that powers the drift cars also powers articulated forklift trucks, anti-gravity racers, hovercrafts, and bikes. This proves the underlying physics model is robust and flexible enough to handle whatever your project requires in the future, from simple cars to complex, multi-part machinery.
