Comparing different versions of the new wheel model's behavior near zero velocity in Vehicle Physics Pro. The latest iteration (blue) resolves the stopping force causing overshoot and oscillation when braking to a stop at high inertia / low substeps. Plots: closed-loop stop, force vs. velocity across inertias, and burnout spin-down case.

New Wheel Dynamics Model development issue: incorporating lateral displacement into the longitudinal equations introduces a discontinuity in the momentum derivatives. We need to review the combined-force calculations to properly accommodate the new longitudinal dynamics model.

Testing the effects of the inertia tensor on vehicle handling using the new Kinematic Wheel Colliders in Vehicle Physics Pro (Unity WheelCollider-free). Turns out the impact is very subtle compared to the legacy wheel colliders, suggesting yet another design flaw in Unity/PhysX WheelColliders.

Open vs. locked differential. A locked differential forces both drive wheels to rotate at the same rate, which can improve traction on slippery terrain. With an open differential, if one wheel loses traction, the available drive torque is limited by that wheel, so both wheels effectively lose tractive capability.

A visual explanation of the Anchor property in Vehicle Physics Pro’s Wheel Collider.

The anchor position defines the point in the suspension travel where the suspension is anchored to the vehicle. It does not change the suspension’s properties, only the ride height.

I'm deciding whether a mechanical animation system should be built on a current state plus deltas, or modeled against an absolute offsets.

State plus delta is the easiest to model correctly but suffers from error accumulation, noise, and inability to jump to a given state.

Absolute offsets (like the normal Unity animation rigging does) allows jumping directly to given states and can participate in constraints. It can also suffer from error accumulation and introduces modelling oddities.

Now this is good mesh density for a racing track 3D model.

~10,000 triangles for a single 60 m patch. The full circuit comes in at nearly 1 million (~960,000) triangles, split into around 96 individual meshes for optimal physics processing.

Inside the code of Vehicle Physics Pro. This is TireFrictionBase, the base class for every tire model implementation in VPP. You can implement any tire friction model and plug it directly into VPP. For example, you could run two instances of the exact same vehicle, each with a different tire model, and compare their behavior.

Visualizing Slip Ratio (left) and Slip Angle (right) as calculated by Vehicle Physics Pro. As part of the ongoing redesign of the tire flex model, we need to ensure that these calculations remain perfectly smooth and continuous across their full range.

News for Vehicle Physics Pro users: VPP has been upgraded to SDK v9.8. The main improvement is that it no longer requires Unity’s Legacy Input Manager.

The update is live now for Enterprise license holders. Professional and Community editions will follow soon.

Summer brings a slower pace, but we’re still pushing forward with these ongoing developments:

🔹 Removing dependencies on Unity’s Legacy Input Manager.

🔹 Refining tire compliance (tire flex — stiffness and damping) in the friction model.

🔹 Exploring new ways to implement kinematic suspension from real-world data.

As always, feel free to reach out for a good tech discussion!

#VPPDev #Unity #MadeWithUnity #IndieDev #GameDev #ScreenShotSaturday #Physics #GamePhysics #TireSimulation

Upcoming work includes completing the new VPP Input Manager with support for Unity’s Input System, and major improvements to the tire contact model and its connection to steering force feedback.

Hitting a bump on the highway at 220 kph / 136 mph 😳 There's little the driving assists (ABS, ESC, etc.) can do here…

In #astrophysics it is often talked about how big objects deflect smaller ones. In may head this looks way too cartoonisch. Like when two objects in a #gameengine collide, bug out and get just violent tossed around 😂 #gamephysics Asteriods getting to close to the sun just do a #tf2 funny ragdoll when they get yeeted back out into the void.

Testing the braking assistance in tough conditions: decelerating from 130 to 0 km/h in 4.5 seconds while entering a curve and going downhill.
