Collision spheres

Hi there
Anyone know of any tutes or documentation on collision spheres? Or even a basic workflow? I've tried a few things but so far haven't been able to figure them out.

Cheers,

Gerard

I would be also interested in this.

MadCar guys really need to update the documentation...

Yes...
Sorry... it is really black hole in documentation.
I will fix it on this week.

Think I figured it out. The Collision Spheres are used to represent the Car within the Madcar cage, NOT the objects that the vehicle is colliding with. Basically just place them within the car body, loosely representing the boundaries of said car body.

Was the documentation updated? It seems like the same manual has been on the product page for about a year now.

Collisions in MadCar.
There are 2 types of collisions to be calculated in MadCar simulation
1. Collisions between the wheels and the ground
2. Collisions between ”Collision Spheres" and the ground.
By default, a car's body does not simulate the possible collision with obstacles or the ground in a rollover.
If you need to simulate such an event, you need to add”Collision Spheres" to MadCar rig.  Place them so that their combined volume is repeating the shape of your vehicle. Try to keep number or spheres as little as possible (optimal number is 10-20), otherwise it may slow down the process of simulation. The “Rigidness” parameter controls the stiffness of the collision, and the parameter “Grip” controls friction.
Obstacles that you are going to impact your car should be included in the geometry of the surface.
Collision Spheres usage example:
