R-Tune Vehicle Physics

Fast and easy-to-setup custom C++ based vehicle physics solution for arcade and simcade vehicles.

Please note: Epic only allows updates for the latest 3 engine versions. Please make sure that you are at least on version 5.2 to receive updates. This plugin supports all versions but will need to be manually compiled for legacy engine versions.

Current Version: v1.1.7 Release

The most powerful and flexible vehicle system available

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 arcade or simcade 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!
