"Jaggy" Collisions between box (car) and mesh (track)

Post by AshMcConnell »

Hi Folks,

I have been trying to track this problem down for a while. I am using Bullet for collision detection, but a custom physics engine written by a physics professor friend of mine.

When the car is "bottoming out" on the track the collision seems to be in the wrong direction (the normal seems to point to the back of the car), I expect the car to scrape along on the chassis. Is there anything I can do to make the collisions smoother?

Here is a video showing the problem. http://www.youtube.com/watch?v=wKl4iatGxf8

There are no problems when I increase the height of the suspension.

Thanks for your help
All the best,
Ash

In case anyone has similar problems (I know it's a bit specific). I solved the problem by increasing the margin on the box and decreasing the collision material's damping (to near zero) in our own custom built physics engine.

Hope this helps!
All the best,
Ash
