Tread example - Making holes in the ground

[mariofaragalla]

Hello Steve,

I am just a beginner and I am trying to understand how the library functions. I don't know if this the best place to ask but I don't know where else could I. I am following the tread example and I made some modifications. I wanted to make holes in the ground so that I can simulate the disturbance that happens to the vehicle. I changed the ground to be a rectangle with holes but I can't make the Contact to Sphere block to generate a contact plane with holes in it. I've also tried to modify the block but it seems that there are a lot of hidden parameters that I can't access. I would like to know what would you suggest that I do. Thank you :)

I even tried to eliminate the plane under the left wheels and it made no difference, and I don't know why. Please check the following video.
