Chaos Vehicles: Lateral Slip Graph units and calculation principle (Normalized vs Absolute)

Development Programming & Scripting Blueprint

Hi everyone,

I am setting up a drift vehicle using Chaos Physics and need to clarify how the Lateral Slip Graph values are calculated in ChaosVehicleWheel. There is a lot of conflicting information in tutorials (some use 0 to 1 normalized curves, others use absolute values like 1500–3000).

Could someone explain the exact math behind it?

  1. Units: What are the exact measurement units for the X and Y axes? Is X strictly Slip Angle in degrees, and is Y a normalized multiplier or raw Force in Newtons?

  2. Scaling: When does the engine expect a normalized peak (1.0–1.2) vs. absolute high numbers (1500+)? How does this curve interact with Friction Force Multiplier?

  3. Drift Setup: What is the best practice for aligning this curve to get a controllable, predictable slide?

Thanks!
