How do I get more detailed sphere collision?

My player character is a ball that you roll around. the problem is that the default sphere simple collision mesh isn’t detailed enough so when the ball is spinning fast, the vertices catch on whatever it’s colliding with and it makes the ball jump up in the air. So how do I get a more detailed simple sphere collider? I’ve tried messing around in maya and looking at youtube tutorials, but whenever I import my custom sphere with its custom collision, unreal just changes it to the default simple sphere collider.

Well if your ball is spinning real fast, that means it has a set speed. you could try to make a Box Collision on the items it hits with a Beginoverlap and make it slow the Ball down and when EndOverlap it speeds back up
