I tried more on making vehicles, once you learn it's easy
For angrypig: This time I did like you told me, parenting the wheels without using bones and it worked with no problems.
I'm having a slight problem, the center off mass is offset in 2 directions, I fixed it only in 1, how can I set a second value for another axis?
The model is not mine. I downloaded it from thefree3dmodel.com , it's a van from Alan Awake game.
I tried this
return {mass:2500, steering:3.0, steering_ecf:60, centering: 3.0, centering_ecf: 40, com:{y:-0.8,z:-0.1}};
It just changes the first direction. Anyway I keep getting a console warning about a center of mass error. By default it's the vehicle mesh origin? Cos in Blender I set it right, but in Outerra it's slightly offset on the front.
