R-Tune Vehicle Physics: Vehicle System for Games & Animation

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

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 arcade-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!

Features:

• Stable physics and behavior at low frame rates (<15fps)

• Includes both simple arcade and complex advanced powertrains and handling behavior

• Drift assist torque implementation

• Brake-to-Reverse or gear ratio reverse options

• Anti-Gravity system

• Kart jump ability

• Works with Sequencer and Movie Render Queue

• Vehicle system compliant with spline based animations

• Vehicle behavior is fully extendable in blueprints

• Fully replicated with anti-cheat features

• Replication works seamlessly with blueprint physics modifications and custom extensions

• Compatible with other movement replication systems like Smooth Sync or custom replication movement solution

• Spring/Damper suspension with modified sphere trace for smoother behavior

Current version 1.3.6
