Ball jumping when moving over 2 cubes

Hi, i have created a ball using rigibody, all works great. However if i have two platforms i.e cubes, position them together to make a bigger platform, even through the tops are set the same position and there are no gaps between the platform, the ball jumps a little when rolling over the connected edges.

Any ideas as to why this is happening?

can anybody help at all, driving me mad lol

try intersecting the objects and seeing if it the ball jumps where it intersects first. If that is the case one collider is probably higher than the other.

Iv tried instersection and still the same problem.

How do you position the colliders?

I have set the position of the cubes to be the same.

I know this question is from several years ago, but I just fixed this problem by using a box collider on an object called “level” in my case, and inside that object I just placed all of the plataforms, also you will need to resize the collider to make it the size of the plataforms.

Basically instead of placing one collider for each plataform, when plataforms are together just place one.
