I have made a test application where I have three static boxes of the dimensions 10x1x10. These three boxes are placed right next to each other so they actually form a 30x1x10 box. When I let a sphere roll from one end to the other, it seems to bounce when
it rolls over the seams between the boxes, even though the boxes are placed right next to each other in the same level. Can anybody explain this? Can I do anything about it?
