Fancy Car Physics Issue

Troubleshooting physics
1

Hello Guys,
I’m using fancy car with some city model downloaded from sketchfab and the car behaves strange when put inside that city model (see sample video). When put on a simple Box it works fine (stable). I’m trying to understand what should be done (maybe tuning the suspension?) in order to make it work fine with this city model?
Thank You.

I think your city model floor needs more triangles.

  1. What’s the physics time step?
  2. Car has the same scale in both tests?
  3. Can we see it with physics debug enabled?

Thanks Guys. I found the issue. I didn’t use MeshCollisionShape for this static city model and it seems that it is mandatory for this kind of models (static). Instead, I have used CollisionShapeFactory.createDynamicMeshShape(model) which was much less accurate and much much slower to produce
