We’ve got a reproducible bug in a very simple project where a basic vehicle setup is using wheel colliders. Hit play and the wheels work fine, change any setting on the vehicles rigidbody such as: Interpolation, Collision Detection, what layer the game object is on, drag, mass, anything, and the Whe…

Appears there’s a couple of Wheel Collider fixes in the release notes of 6000.0.23 :crossed_fingers:

A customer told me it’s now working fine :slight_smile: But I haven’t tried myself.

Maybe some settings of the WheelCollider were reset to their default values? (i.e. radius = 1). Showing the Wh…
