Vehicle rigging notes

These are my own notes for rigging vehicles. Currently adapted to rigging trucks, as I've had to rig quite a few of these recently.

Documentation

Base rig

Main GameObject + child mesh + child collider

Rigidbody: Total weight

VPVehicleController, VPTelemetry, VPStandardInput

WheelColliders

Center of Mass (CoM)

Inertia

Vehicle setup

Driveline

Steering

Brakes

Tires (Parametric Model)

Single truck wheels:

Adherent: 0.5, 0.8
Peak: 1.6, 0.9
Limit: 8, 0.7
ABCD: 0.6, 0, 0.2, 0

Twin truck wheels (use VPTireFrictionModifier):

Adherent: 0.5, 0,9
Peak: 1.8, 1.1
Limit: 8, 0.9
ABCD: 0.8, 0, 0.15, 0

Engine

Gearbox

Solver

Effects

Suspension and dynamics

Suspension

Rolling Friction

Aerodynamics

Center Of Mass

Safety aids

ABS, ECS, ASR, TCS

Special vehicles

Tandem + Trailer

Usually the combined mass is specified. Use 55% for tandem, 45% for trailer.
